Total and subshell-selective charge exchange cross sections and the corresponding reaction rate coefficients for Neq+-H (q=6–10) collision systems are calculated by utilizing the two-center atomic orbital close-coupling (TC-AOCC) method at impact energy between 0.1 keV/u and 500 keV/u. Good agreements with the experimental and other theoretical results are found for the total charge transfer cross

The 1,3Po states of exponential cosine-screened heliumlike atoms Atom. Data Nucl. Data Tables (IF 1.8) Pub Date : 2021-08-24 Xi Wang, Zishi Jiang, Sabyasachi Kar, Yew Kam Ho
We investigate the singly-excited and doubly-excited 1,3Po states of screened-heliumlike atoms (Z=3-10), starting from Li+ to Ne8+ under the influence of exponential cosine-screened (ECS) Coulomb potentials. Pseudo-random-parameters dependent correlated exponential wave functions are used to represent the correlation effects between the charged particles. The singly-excited 1s2p 1,3P states are also
