摘要
In the present work a special computational program Scilab (Scientific Laboratory) in the complex rotation method has been used to calculate resonance parameters of (2s(2)) S-1(e), (2s2p) P-1,3(0)) and ((3s(2)) S-1(e), (3s3p) P-1,3(0)) states of helium-like ions with Z <= 10. The purpose of this study required a mathematical development of the Hamiltonian applied to Hylleraas wave function for intrashell states, leading to analytical expressions which are carried out under Scilab computational program. Results are in compliance with recent theoretical calculations. (C) 2014 Elsevier Ltd. All rights reserved.
