摘要
当无限深势阱中加入δ函数势后,受影响最大的是基态,当δ函数势由排斥变为吸引时,基态能量由正变负,而其他能级保持为正.
Once the infinitely deep well decorated with a Dirac delta function potential at the center, the ground states can be greatly influenced, and as the potential changes from repulsive to attractive, the ground state energy decreases from positive to negative, while excited state energy remains positive.
