摘要:

我们得到了任意自旋轨道量子数K的具有Poschl-Teller双环库仑势(PTDRSC)的Dirac方程的精确解.研究了自旋为1/2的粒子在该势场中的相对论性散射振幅。波函数用K/2 Pi尺度上连续态的超几何级数表示。在非相对论极限下,我们的解收敛于薛定谔解。在高温下,计算了配分函数,以研究某些热力学性质的行为。

英文摘要:

We obtain the exact solution to the Dirac equation with the Poschl-Teller double ring-shaped Coulomb (PTDRSC) potential for any spin-orbit quantum number K. The relativistic scattering amplitude for spin 1/2 particles in the field of this potential has been studied. The wave functions are expressed in terms of the hyper-geometric series of the continuous states on the K/2Pi scale. A formula for the phase shifts has also been found. In the nonrelativistic limits, our solution to the Dirac system converges to that of the Schrödinger one. At the high temperature, the partition function is calculated in order to study the behavior of some thermodynamic properties.
