计算了能量范围从10 eV/u到10 MeV/u的质子-氦碰撞中的电荷转移截面。四种不同的方法（全量子时间无关和时间相关的方法，分子和原子基组半经典方法）有效的在不同的能量制度已被用来计算单电子捕获的部分和总截面。与以前的理论计算和实验测量结果进行了比较，所使用的不同的理论方法被证明是互补的描述电荷转移反应。一个适合的截面，有效的碰撞能量从10 eV/u到10 MeV/u的基础上，这些结果。
The cross section for charge transfer in proton-helium collisions has been computed in the energy range from 10 eV/u up to 10 MeV/u. Four different methods (full quantal time-independent and time-dependent methods, molecular and atomic basis set semi-classical approaches) valid in different energy regimes have been used to calculate the partial and total cross section for single-electron capture. The results are compared with previous theoretical calculations and experimental measurements and the different theoretical methods used are shown to be complementary for describing the charge transfer reaction. A fit of the cross section, valid for collision energies from 10 eV/u up to 10 MeV/u is presented based on these results.
