\psi(x) = \int dp \exp{ipx} \psi(p)

V(p) = \int \exp{-ipx} V(x)  dx

In momentum representation :

\frac{p^2}{2m} \psi(p) + \int dp^{\prime} V(p-p^{\prime}) \psi(p^{\prime}) = E \psi(p)

做提前请注意题目给出的是坐标表象下的而非狄拉克符号表示的，请不要直接替换，请使用规范方法

这论坛Latex老出问题；而且在写的时候都不能预览真是醉！  V(p) 是 V(x) 的傅里叶变换，或者逆变换，看你怎么看！...
