Photoelectron Angular Distributions for Photoionization of the Be-like B⁺ Ion

Dae-Soung Kim and Hak-Chul Kang¹

(Received September 15, 2004)

Photoelectron angular distribution asymmetry parameters β for the process leaving the ions in the B²⁺ np and ns (n=2 and 3) states from the ground and excited 2s2p ^1,3P states of Be-like B⁺ ion have been calculated. The other final ionic states of B²⁺ are states leading to a constant β=2. A noniterative variational R-matrix approximation has been used for the present calculation of transition strengths. With almost overlapped agreement between the length and velocity gauges, autoionizing doubly excited resonance structures converging to B²⁺ 3s, 3p, and 3d thresholds are clearly appeared in the present β parameters. ©2005 The Physical Society of Japan
