摘要
一般地,WKB方法只能用于估算高激发态(即大量子数)能量,但在一定条件下,经适当修正,WKB方法可用于束缚态能量的近似计算,例如;氢原子能级公式和球谐振子能级公式也可由 WKB方法导出.
Generally,the WKB method can only use in estimating and calculating energies of high excitations (i. e large quantum numbers). But,in a certain condition, the WKB method can use in approximate calculating of bound state energies by proper corrections. Example E_(n) = f4e^(4)/2h^(2)N^(2)) (N = n+l,n、l = 0,1,…) (Hydrogen -like atom energy formula) and E_(nl)= (2n + l + 1)hω(n,l = 0,1,…) (spherical harmonic oscillator energy formula) can both be calculated by the WKB method.
