|Title:||Influence of exchange distortion potential on electron impact excitation of B+||Authors:||Guo-xin, C.
|Issue Date:||19-Jun-1998||Citation:||Guo-xin, C.,Ong, P.P.,Ting, L. (1998-06-19). Influence of exchange distortion potential on electron impact excitation of B+. Chemical Physics Letters 289 (5-6) : 428-432. ScholarBank@NUS Repository.||Abstract:||The relativistic distorted-wave method was used to calculate electron impact excitation of B+. The target states were described by a 133-level MCDF configuration-expansion. The relativistic continuum orbitals were calculated in the potential field of the frozen target-ion charge distribution. The semiclassical and free-electron-gas approximations of Riley and Truhlar and the Dirac-Fock-Slater (DFS) approximation were used in the calculation of exchange distortion potentials. It is found that the exchange potentials have significant influence on collision strengths especially for spin-forbidden transitions. In particular, DFS potentials are less suitable compared with the other potentials.||Source Title:||Chemical Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/96912||ISSN:||00092614|
