"The energy eigenvalues and eigenfunctions of the Schrodinger equation for Eckart potential as well as the parity-time-symmetric version of the potential in three dimensions with the centrifugal term are investigated approximately by using the Nikiforov-Uvarov method," researchers in Xian, People's Republic of China report.
"To show the accuracy of our results, we calculate the energy eigenvalues for various values of n and l. It is found that the results are in good agreement with the numerical solutions for short-range potential (large a)," wrote A.P. Zhang and colleagues.
The researchers concluded: "For the case of 1/a double right arrow i/a, the ...
