In this Letter the approximately analytical scattering state solutions of the l-wave Schrödinger equation for the Manning-Rosen potential are carried out by a proper approximation to the centrifugal term. The normalized radial wave functions of l-wave scattering states are presented and the calculation formula of phase shifts is derived. It is well shown that the poles of the S-matrix in the complex energy plane correspond to bound states for real poles and scattering states for complex poles in the lower half of the energy plane. We consider and verify two special cases: the l=0 and the s-wave Hulthén potential. 相似文献

Spin symmetry in the relativistic modified Rosen-Morse potential with the approximate centrifugal term 下载免费PDF全文
By applying a Pekeris-type approximation to the centrifugal term, we study the spin symmetry of a Dirac nucleon subjected to scalar and vector modified Rosen-Morse potentials. A complicated energy equation and associated two-component spinors with arbitrary spin-orbit coupling quantum number k are presented. The positive-energy bound states are checked numerically in the case of spin symmetry. The relativistic modified Rosen-Morse potential cannot trap a Dirac nucleon in the limiting case α→ 0. 相似文献

In this paper, using the exponential function transformation approach along with an approximation for the centrifugal potential,
the radial Klein-Gordon equation with the vector and scalar Hulthén potential is transformed to a hypergeometric differential
equation. The approximate analytical solutions of t-waves scattering states are presented. The normalized wave functions expressed in terms of hypergeometric functions of scattering
states on the “k/2π scale” and the calculation formula of phase shifts are given. The physical meaning of the approximate analytical solution
is discussed.

The approximately analytical scattering state solutions of the l-wave Klein-Gordon equation with the unequal scalar and vector Hulthén potentials are carried out by an improved new approximate
scheme to the centrifugal term. The normalized analytical radial wave functions of the l-wave Klein-Gordon equation with the mixed Hulthén potentials are presented and the corresponding calculation formula of phase
shifts is derived. It is well shown that the energy levels of the continuum states reduce to those of the bound states at
the poles of the scattering amplitude. Some useful figures are plotted to show the improved accuracy of our results and two
special cases for s-wave (l=0) and for l=0 and equal scalar and vector Hulthén potentials are also studied briefly. 相似文献
