Abstract
A Quesne-like ring-shaped spherical harmonic oscillator potential is put foword and studied for spin 1/2 particles based on the Dirac equation， the Dirac Hamiltonian contains a scalar and a vector Quesne-like ring-shaped harmonic oscillator potentials. Setting Σ ＝ S ( r )+V( r )=0,we obtain the bound state solutions and eigenenergies with the two-component approach. The result shows the pseudospin symmetry exists in the Quesne-like ring-shaped harmonic oscillator potential. The general properties of both the ring-shaped spherical harmonic oscillator potential and the ring-shaped non-spherical harmonic oscillator potential are discussed.
基于狄拉克方程，提出并研究了自旋为1/2粒子的类quese环形球谐子势，狄拉克哈密顿量包含一个标量和一个矢量类quese环形谐振子势。设Σ = S (r)+V(r)=0，用双分量法得到束缚态解和特征能。结果表明，类quesne环形谐振子势中存在赝自旋对称性。讨论了环形球面谐振子势和环形非球面谐振子势的一般性质。
