以库仑屏蔽势为模型,用蒙特卡罗哈密顿方法对库仑屏蔽势束缚态进行研究,并把结果和传统的数值解一维薛定谔方程的方法相比较,在基态或激发态,都得出相一致的结果.
We investigate non-s bound states in a screen Coulomb potential V( r ) = - λ exp ( - αr )/r, with different algorithms. The Schrodinger equation is solved using 4-step Runge-Kutta Method and Monte-Carlo approach. We analyzed errors of the MCH method. The energy spectrum and wave function in ground state and excited state agree well with those of 4-step Runge-Kutta method.
