Finally , a specific analysis is made for our results . because we have considered the correlation between the confined and non - confined direction of the wire , the binding energy is improved and correspondingly the threshold energy is enhanced , which results in the declinement of the photoionization cross - section 最后对所得结果进行了详细的讨论,山于我们选取的波函数考虑到限制方向与非限制方向的相关性因素,从而提高了杂质的束缚能(在宽阶时尤为明显x即提高了所谓的阈能( e ,导致了光电离截面值的减小
In particle physics, the threshold energy for production of a particle is the minimum kinetic energy a pair of traveling particles must have when they collide. The threshold energy is always greater than or equal to the rest energy of the desired particle.
