A COMPREHENSIVE X-RAY ABSORPTION MODEL FOR ATOMIC OXYGEN
(IOP PUBLISHING LTD, 2013-12-10)
An analytical formula is developed to accurately represent the photoabsorption cross section of O I for all energies of interest in X-ray spectral modeling. In the vicinity of the K edge, a Rydberg series expression is ...
Photoionization of confined Ca in a spherical potential well
(AMER PHYSICAL SOC, 2013-01-09)
The photoionization cross section of the Ca atom, confined by a spherical annular potential, has been calculated using a modification to the Belfast R-matrix code for a variety of depths of the confining potential. The ...
Probing confinement resonances by photoionizing Xe inside a C-60(+) molecular cage
(AMER PHYSICAL SOC, 2013-11-01)
Double photoionization accompanied by loss of n C atoms (n = 0, 2, 4, 6) was investigated by merging beams of Xe@C-60(+) ions and synchrotron radiation and measuring the yields of product ions. The giant 4d dipole resonance ...
