利用产生、湮灭算符构造费米系统的波函数

Constructiong wave function of fermi system by using the producing and eliminating operators

讨论了费米系统在中心力场中运动时，从单粒子能级εj上一对费米子出发，构造了单泣子态的产生、湮灭算符．然后引入总粒子数算符，利用产生、湮灭算符构造了k对费米子的波函数，并进行了归一化。

The author constructs the producing and eliminating operators of the single particle state from a pair of Fermi at the single particle energy level εj; and deduces the wave function of k pairs of Fermi and normalizes it by using the operators of the total amount of particles and the producing and eliminating operators.
