Coherent Control of Atomic Beam Diffraction by Standing Light
Quantum interference is shown to deliver a means of regulating the
diffraction pattern of a thermal atomic beam interacting with two standing wave
electric fields. Parameters have been identified to enhance the diffraction
probability of one momentum component over the others, with specific
application to Rb atoms.Comment: 5 figure

Two-photon photoelectron spectrum of methyl iodide through a dissociative intermediate state
The two-photon photoelectron spectrum of methyl iodide was recorded in a magnetic bottle time-of-flight spectrometer. As absorption of the first photon is resonant with the dissociative A-state continuum of methyl iodide, the experiment corresponds to a bound-free-bound transition. A progression in the C-I stretching vibration is observed, which corresponds, in a simplified picture, to the dissociation coordinate. The results agree well with recently published two-photon ZEKE spectra of CH3I. This similarity has impact on an ongoing discussion about discrepancies between calculated and measured intensities in two-photon ionization spectra.close111
