摘要
Deng-Fan potential originally appeared many years ago as an attractive proposition for molecular systems.On the contrary to the ground state of one-dimensional Schro¨dinger equation,this potential fails to admit exact analytical solutions for arbitrary quantum number in both relativistic and nonrelativistic regime.Because of this complexity,there exists only few papers,which discuss this interesting problem.Here,using an elegant ansatz,we have calculated the system spectra as well as the eigenfunctions in the general case of unequal vector and scalar potentials under Klein-Gordon equation.
Deng-Fan potential originally appeared many years ago as an attractive proposition for molecular systems. On the contrary to the ground state of one-dimensional Schr6dinger equation, this potential fails to admit exact analytical solutions for arbitrary quantum number in both relativistic and nonrelativistic regime. Because of this complexity, there exists only few papers, which discuss this interesting problem. Here, using an elegant ansatz, we have calculated the system spectra as well as the eigenfunctions in the general case of unequal vector and scalar potentials under Klein-Gordon equation.
