摘      要：We investigate the electron capture processes of N4+(1s22s)colliding with He(1s2)in the energy range of 10-1700 eV/amu using the quantum-mechanical molecular-orbital close-coupling(QMOCC)*** and stateselective single-electron capture and double-electron capture(SEC and DEC)cross sections are obtained and compared with other available *** results agree better with the experimental data in both trend and magnitude when the electron translation factor(ETF)effects are *** results indicate that both the SEC and DEC processes play important roles in the considered energy *** the SEC processes,the N3+(1s22p2)+He+(1s)states are the dominant capture states,and the N^2+(1s^2 2s2p^2)+He^2+states are the main DEC states.
