Double photoionization of helium from the 1s2p P-3 excited state

摘要

Time-dependent close-coupling (TDCC) calculations are carried out for the double photoionization of Helium in the 1s2p P-3 excited state. TDCC l(1)l(2)L results are presented for the total and energy differential cross sections for the 1s2p P-3 term. TDCC l(1)j(1)l(2)j(2)J results are presented for the total and energy differential cross sections for the 1s2p P-3(0,1,2) levels. Differences found between the level resolved double photoionization cross sections are due to varying degrees of continuum correlation found in the outgoing two electrons.
