用分子轨道方法研究了低能区(E<；或约=20keV Amu-1)C4+和C6+与He碰撞中的电子俘获。用从头算方法确定了相互作用能和波函数。在散射计算中考虑了双电子平移因子，从而可以严格地计算(NL)截面。对于C4+He碰撞，在低能量碰撞能量下，电子对C2+(2S2)的双俘获占据主导地位，而在较高能量下，对C3+(2p)态的单电子俘获占据主导地位。对于C6+He体系，C5+(3l)产物态随碰撞能变化很快，C5+(3d)态和C5+(3p)态在低能时对总截面的贡献最大，高能时C5+(3p)态对总截面的贡献最大。
Electron capture in collisions of C4+ and C6+ with He has been studied in the low energy region (E<or approximately=20 keV amu-1) using the molecular orbital method. An ab initio calculation was performed to determine the interaction energies and wavefunctions. Two-electron translation factors were included in the scattering calculations so that the (nl) cross sections could be rigorously evaluated. For C4+He collisions, double electron capture to C2+(2s2) dominated the scattering of low collision energies, while at higher energies single capture to the C3+(2p) state was the dominant channel. For the C6+He system, the C5+(3l) product states varied rapidly with collision energy with the major contribution to the total cross section arising from the C5+(3d) state at low energies and the C5+(3p) state at high energies.
