【摘要】 应用微扰方法研究了一维量子阱中突然δ势介入后对体系的能级影响.研究表明,δ势对体系的奇宇称态没有影响,对体系的偶宇称态则使能级有一个恒定的移动,移动的大小依赖于δ势的作用强度.更多还原

【Abstract】 The paper studied the effect of a suddenly intruded δ potential on the energy level of a one-dimensional quantum well by perturbation method.It is found that δ potential has no effect on the odd parity states of the system but it makes the energy level of the even parity states have a constant shift,and the degree of the shift depends on the intensity of δ potential.更多还原
