Reply To “Comment On ‘Photodetachment In Combined Static And Dynamic Electric Fields’”, A. R. P. Rau, Chitra Rangan
Physics Publications
While distortion of the initial negative-ion state by a strong static electric field can have observable effects, the effect attributed by the authors of the preceding Comment [Phys. Rev. A 64, 037401 (2001)] to a cross term between the detaching laser field and the static field is spurious, an artifact of their procedures. Other points of dispute are also clarified.
Optimally Shaped Terahertz Pulses For Phase Retrieval In A Rydberg-Atom Data Register, Chitra Rangan, P.H. Bucksbaum
Optimally Shaped Terahertz Pulses For Phase Retrieval In A Rydberg-Atom Data Register, Chitra Rangan, P.H. Bucksbaum
Physics Publications
A terahertz pulse was designed to implement a search algorithm on a quantum data register. Phase information stored in a Rydberg wave packet was optimally retrieved through the interaction with the pulse. Careful attention was paid to the smooth switch on and switch off of the terahertz pulse. Furthermore, the possibility of designing an optimal pulse that can achieve not only a desired target state of an atom, but also implement a desired algorithm was shown.

Quantum Phase Retrieval Of A Rydberg Wave Packet Using A Half-Cycle Pulse, J. Ahn, D.N. Hutchinson, Chitra Rangan, P.H. Bucksbaum
Physics Publications
The half-cycle pulse (HCP) was used to search for information stored as phase in a Rydberg wave packet. Phase information coded in a Rydberg quantum register was retrieved through the impulsive interaction of HCP. In general, results of the study point to the use of HCPs as general tools for analysis for unknown wave packet.
Measurement Of The Hyperfine Structure Of The 4d2d 3/2,5/2 Levels And Isotope Shifts Of The 4p2p 3/2 ? 4d2d3/2 And 4p2p 3/2 ? 4d2d5/2 Transitions In Gallium 69 And 71, Steven J. Rehse, W.M. Fairbank Jr., S.A. Lee

The hyperfine structure of the 4d2D3/2,5/2 levels of 69,71Ga is determined. The 4p2P3/2 ? 4d2D3/2 (294.50-nm) and 4p2P3/2 ? 4d2D5/2 (294.45-nm) transitions are studied by laser-induced fluorescence in an atomic Ga beam. The hyperfine A constant measured for the 4d2D5/2 level is 77.3 ± 0.9 MHz for 69Ga and 97.9 ± 0.7 MHz for 71Ga (3s errors). The A constant measured for the 4d2D3/2 level is -36.3 ± 2.2 MHz for 69Ga and -46.2 ± 3.8 MHz for 71Ga. These measurements correct sign errors in the previous determination of these constants. For 69Ga the hyperfine B constants measured for the …
Lamb Shift In He+: Resolution Of A Discrepancy Between Theory And Experiment, A. Van Wijngaarden, F. Holuj, Gordon W. F. Drake
Lamb Shift In He+: Resolution Of A Discrepancy Between Theory And Experiment, A. Van Wijngaarden, F. Holuj, Gordon W. F. Drake
Physics Publications
The Lamb shift in helium ions were investigated to verify or remove a discrepancy between theory and experiment by the anisotropy method. The method was used for the elimination of residual polarization sensitivity of the photon detectors. The results showed that the experimental value of a Lamb shift were in agreement with the theoretical values.
