The neutron provides a simple yet dynamic nuclear system to study the Standard Model of Particle Physics. The process of transforming a neutron into a proton, an electron, and an antineutrino contains a wealth of information in the decay rate and the kinematics of the emitted particles. Precision measurements of angular correlations in neutron βdecay can lend insight to the structure of the weak interaction and probe for physics beyond the Standard Model. The UCNA experiment at the Los Alamos Neutron Science Center is the only experiment to use ultracold neutrons to perform such a measurement, determining the βasymmetry parameter ...
Directional Limits On Persistent Gravitational Waves Using Ligo S5 Science Data, J. Abadie, Marco Cavaglia
Directional Limits On Persistent Gravitational Waves Using Ligo S5 Science Data, J. Abadie, Marco Cavaglia
Marco Cavaglia
The gravitationalwave (GW) sky may include nearby pointlike sources as well as stochastic backgrounds. We perform two directional searches for persistent GWs using data from the LIGO S5 science run: one optimized for pointlike sources and one for arbitrary extended sources. Finding no evidence to support the detection of GWs, we present 90% confidence level (C.L.) upperlimit maps of GW strain power with typical values between 2  20 x 10^{50} strain^{2} Hz^{1} and 5  35 x 10^{49} strain^{2}Hz^{1}sr^{1} for pointlike and extended sources, respectively. The latter result is the first ...

Firstprinciples full potential linear muffintin orbitalgeneralized gradient approximation electronic structure calculations of the new mediumT_{c} superconductor (MTSC) MgB_{2} and related diborides indicate that superconductivity in these compounds is related to the existence of P_{x,y}band holes at the γ point. Based on these calculations, we explain the absence of mediumT_{c} superconductivity for BeB_{2}, AlB_{2}, ScB_{2}, and YB_{2}. The simulation of a number of MgB_{2}based ternary systems using a supercell approach demonstrates that (i) the electron doping of MgB_{2} (i.e., MgB_{2y}X_{y} with X=Be, C ...

Comparing Experts And Novices In Solving Electrical Circuit Problems With The Help Of EyeTracking, David Rosengrant, Colin Thomson, Taha Mzoughi
David Rosengrant
In order to help introductory physics students understand and learn to solve problems with circuits, we must first understand how they differ from experts. This preliminary study focuses on problemsolving dealing with electrical circuits. We investigate difficulties novices have with circuits and compare their work with those of experts. We incorporate the use of an eyetracker to investigate any possible differences or similarities on how experts and novices solve electrical circuit problems. Our results show similarities in gaze patterns among all subjects on the components of the circuit. We further found that experts would look back at the circuit while ...
PreService Physics Teachers And Physics Education Research, David Rosengrant
PreService Physics Teachers And Physics Education Research, David Rosengrant
David Rosengrant
Training preservice teachers requires, among other things, content knowledge, pedagogical skills and pedagogical content knowledge. Teacher preparation programs have little, if any spare time to add more courses/activities to their program. However, I argue in this paper that we, as educators, must enhance the amount of physics education research in our preservice physics teacher training programs. In this study, I analyze the results of two different types of exposure to physics education research (PER) from two different groups of preservice physics teachers in our masters of arts and teaching program. The preliminary results show, for example that the PER ...
A Simple Electric Field Probe In A Gauss's Law Laboratory, Daniel O. Ludwigsen, Gregory N. Hassold
A Simple Electric Field Probe In A Gauss's Law Laboratory, Daniel O. Ludwigsen, Gregory N. Hassold
Gregory Hassold
Early in our calculusbased introductory course, students are introduced to electric fields and sometimes struggle with the abstraction of a vector field. They have less familiarity with the phenomena associated with electric fields, and the connection between phenomena and mathematical formalism is weaker. Our very next topic is Gauss's law.

Vector Acoustic Intensity Around A Tuning Fork, Daniel A. Russell, Justin Junell, Daniel O. Ludwigsen
Daniel Ludwigsen
The acoustic intensity vector field around a tuning fork is investigated. Theory for a longitudinal quadrupole source predicts a welldefined transition between nearfield and farfield, with significant circulation of sound energy in the nearfield. Vector components of the timeaveraged intensity were measured using a twomicrophone intensity probe and found to agree well with predictions from theory. The vector intensity map is interpreted, and shown to provide useful information about the nearfield of an acoustic source.

Supersymmetry And The Tunneling Problem In An Asymmetric Double Well, Asim Gangopadhyaya, Prasanta Panigrahi, Uday Sukhatne
Asim Gangopadhyaya
The techniques of supersymmetric quantum mechanics are applied to the calculation of the energy difference between the ground state and the first excited state of an asymmetric double well. This splitting, originating from the tunneling effect, is computed via a systematic, rapidly converging perturbation expansion. Perturbative calculations to any order can be easily carried out using a logarithmic perturbation theory. Our approach yield substantially better results than alternative widely used semiclassical analyses.

Structure And Bonding Of Au5m (M=Na, Mg, Al, Si, P, And S) Clusters, Chiranjib Majumder, Anil Kandalam, Puru Jena
Anil K. Kandalam
The atomic and electronic structure of Au5M (M=Na, Mg, Al, Si, P, S, and Au) clusters have been investigated using generalized gradient approximation to the density functional theory. Depending on the nature of interaction with different impurity elements a structural transition from planar to nonplanar configuration has been observed in Au5M. With the exception of S, impurities with p electrons (Al, Si, P) yield nonplanar geometries of Au5M clusters, while those with selectrons (Na, Mg) yield planar geometries. The properties of Au5Scluster are anomalous: The cluster not only has a planar geometry, but also is chemically most stable with ...

Anil K. Kandalam
Through a synergetic combination of anion photoelectron spectroscopy and density functional theory based calculations, we have investigated the extent to which the aluminum moieties within selected magnesiumaluminum clusters are Zintl anions. Magnesiumaluminum cluster anions were generated in a pulsed arc discharge source. After mass selection, photoelectron spectra of Mg m Al n ^{−} (m, n = 1,6; 2,5; 2,12; and 3,11) were measured by a magnetic bottle, electron energy analyzer. Calculations on these four stoichiometries provided geometric structures and full charge analyses for the cluster anions and their neutral cluster counterparts, as well as photodetachment transition energies (stick ...
