摘要
导出了激光场中电子被中心势场散射的以分波相移表示的自由-自由跃迁吸收截面理论计算公式,以激光场中慢电子被He原子势场散射为例做了计算,说明对于自由-自由吸收截面,该公式的计算是有效的、方便的。
a formula of the free-free absorption cross section of electron both in the spherically symmetric potential field and in the presence of a laser field has been found . Expressed with the partial wave phase shifts, the formula has been written, The computation for e+He+hw shows that this formula is effective and available for the e + A+hw system.
