关于库仑散射振幅的一点注记
A note on Coulomb scattering amplitude
摘要:
由于库仑散射振幅的分波级数是发散的,因此避免了对分波级数$f^C(θ)$求和。相反,$f^C(θ)$是通过在抛物柱面坐标系中求解薛定谔方程得到的,这不是一种通用方法。在这里,我们表明,一个重建的系列,$(1-\cosθ) ^2f^C(θ)$,既收敛和解析求和。
英文摘要:
The summation of the partial wave series for Coulomb scattering amplitude, $f^C(θ)$ is avoided because the series is oscillatorily and divergent. Instead, $f^C(θ)$ is obtained by solving the Schr{ö}dinger equation in parabolic cylindrical co-ordinates which is not a general method. Here, we show that a reconstructed series, $(1-\cosθ) ^2f^C(θ)$, is both convergent and analytically summable.
