Nondipole effects in photo-double-ionization of He by a vuv photon.
We present a dynamical model-independent, ab initio parametrization of the quadrupole transition amplitude for photo-double-ionization of He. An asymmetry of the triple differential cross section induced by the nondipole corrections is discussed and shown to be significant even for an excess energy as low as 80 eV. We provide predictions for two different kinds of experiments in which nondipole...
متن کاملStrong nondipole effects in low-energy photoionization of the 5s and 5p subshells of xenon
Large nondipole effects are predicted in the angular distribution of photoelectrons from the 5s and 5p subshells of xenon for photon energies below 200 eV. The nondipole parameter g5s exhibits a dispersion-curve variation near the first minimum of the 5s cross section at 35 eV, reaching a minimum value of 20.8 near 40 eV. Rapid variation of g5s is also found near the second minimum of the 5s cr...
متن کاملDramatic nondipole effects in low-energy photoionization: experimental and theoretical study of Xe 5s.
The Xe 5s nondipole photoelectron parameter gamma is obtained experimentally and theoretically from threshold to approximately 200 eV photon energy. Significant nondipole effects are seen even in the threshold region of this valence shell photoionization. In addition, contrary to previous understanding, clear evidence of interchannel coupling among quadrupole photoionization channels is found.
متن کاملNondipole effects in Xe 4d photoemission
We measured the nondipole parameters for the spin-orbit doublets Xe 4d5/2 and Xe 4d3/2 over a photon-energy range from 100 eV to 250 eV at beamline 8.0.1.3 of the Advanced Light Source at the Lawrence Berkeley National Laboratory. Significant nondipole effects are found at relatively low energies as a result of Cooper minima in dipole channels and interchannel coupling in quadrupole channels. M...
