提出了一种新的环形非谐振子势。当标量势等于矢量势时,得到了带势的狄拉克方程的精确界解。通过变量分离法得到了角方程和径向方程。结果表明,归一化角波函数可以用广义关联- legendre多项式表示,归一化径向波函数可以用合流超几何函数表示。得到了精确的能谱方程。求解了系统的基态和几个低激发态。并将这些结果与物理学中的非相对论效应能级进行了比较。列托人。A 340 (2005)讨论了系统的正能态,得出了正确的结论。
A new ring-shaped non-harmonic oscillator potential is proposed. The precise bound solution of Dirac equation with the potential is gained when the scalar potential is equal to the vector potential. The angular equation and radial equation are obtained through the variable separation method. The results indicate that the normalized angle wave function can be expressed with the generalized associated-Legendre polynomial, and the normalized radial wave function can be expressed with confluent hypergeometric function. And then the precise energy spectrum equations are obtained. The ground state and several low excited states of the system are solved. And those results are compared with the non-relativistic effect energy level in Phys. Lett. A 340 (2005) 94. The positive energy states of system are discussed and the conclusions are made properly.
