本文提出了一种新的全量子方法来计算中性碰撞中D1线的展宽和位移系数。该方法基于变相位法和Baranger理论，用散射相移代替散射矩阵元，简化了计算。作为例子，用该方法计算了碱金属原子Rb在150 ~ 800 K温度范围内与缓冲气体He和Ar碰撞时吸收线的展宽和位移系数。通过与其他计算和实验测量结果的比较，在所有情况下的合理协议证明了该方法的有效性和简单性。
In this work, a new full quantum method is proposed to calculate the broadening and shift coefficients of the D1 line in neutral collision. Based on the variable phase approach and Baranger theory, this method calculates the scattering phase shift instead of scattering matrix elements in order to simplify the calculation. As an illustration, this method is used to calculate the broadening and shift coefficients of the absorption lines of alkali metal atom Rb, as it collides with buffer gas He and Ar, in a temperature range from 150 K to 800 K. With a comparison with other calculations and experiment measurements, the reasonable agreements in all cases demonstrate the validity and simplicity of this method.
