摘要: 利用数值计算方法研究了E〉U。、O〈E〈U。和E=Uo时,粒子在一维“方形”势垒中运动时的粒子的概率分布,并给出了概率密度图.从这些图我们可以清楚的看出不同能量的粒子在“方形”势垒散射时的概率分布情况,并讨论了透射系数、反射系数与势垒宽度的关系.

关键词: 概率密度, 势垒

Abstract: By using the numerical method, this paper investigates the probability distribution of a particle moving in the one-dimensional square barrier for three cases: E〉Uo ,0〈E〈U0 and E= U0. We give the probability density figure where the probability distribution evolution in scattering processes in different square barriers can be clearly seen. The relation between the transmissions, reflection coefficients with the barrier height has been ana- lyzed in detail.

Key words: probability distribution, square potential barrier
