库仑相移的再认识
The Coulomb phase shift revisited
摘要:
我们研究了库仑相移,推导和分析了新的和更精确的解析公式。我们认为下一个领导阶项的斯特林近似,并表明,他们是重要的,在小值的角动量$l$和其他制度。我们采用一致逼近法。讨论了我们的表达式在带电粒子低能散射中的应用,并与其它近似方法作了比较。
英文摘要:
We investigate the Coulomb phase shift, and derive and analyze new and more precise analytical formulae. We consider next to leading order terms to the Stirling approximation, and show that they are important at small values of the angular momentum $l$ and other regimes. We employ the uniform approximation. The use of our expressions in low energy scattering of charged particles is discussed and some comparisons are made with other approximation methods.
