L+1/2阶Bessel函数根的一个简单近似解析式

A Simple Approximate Analytic Formula of (L+1/2) order Besser Furction's Radical

1+1/2阶Bessel函数根的表达式已有资料给出但较为复杂,本文从量子力学的角度,用WKB方法给出了一个简单的表达式,从而应用起来很方便。

It's well know that (1+1/2) order Besser furction's radical is too complex. In this paper, from the view of quantum mechanics a simple formula by means of WKB'way has been given to generalize other's results.
