Physics Theses & Dissertations
The magnetic properties of Ce1-xGdx.Al3 have been studied using 155Gd Mossbauer spectroscopy. It has been shown that the magnetic moments of the host GdAl3 are constrained to the basal plane. The magnetic properties of GdAl3 can best be described in the framework of RKKY theory. Prior studies of Ce1-xGdxAl3, have revealed complex magnetic behavior throughout the series. As observed with Mossbauer spectroscopy magnetic ordering occurs for x ≥ 0.5, though not at the reported spin glass temperatures. For x = 0.23 and x = 0.18, the …

Rotationally Resolved Laser Spectroscopy Of The 3s2Σ+ ← 2p2ii Transition In 6li20ne And 7li20ne Van Der Waals Molecules, Chang Jae Lee
Physics Theses & Dissertations
The rotationally resolved absorption spectrum of the 6Li20Ne and 7Li20Ne 3s2Σ+ ← 2p2 II transition has been observed. For each isotope, thirteen vibrational transitions from four vibrational levels (v"=0, 1, 2, and 3) of the lower 2p2 II to six (v’=0, 1, 2, 3, 4, and 5) of the upper 3s*Σ+ electronic state have been rotationally analyzed. Adiabatic potentials and dissociation energies for both states have been obtained through an inverse perturbation analysis. For the 2p2II state, a well depth of 212(5) cm-1 and an …
