“…The purpose of this work is to investigate the bound‐state spectra of DF‐type potential for arbitrary quantum numbers , as well as for both low and high states. Although, some decent results are available, there is a need of systematic analysis in terms of accurate eigenvalues, eigenvalues and other relevant quantities, especially for the situations mentioned earlier. For this, we use the generalized pseudospectral method (GPS), which has been very successful for a number of physically important quantum systems, such as, spiked harmonic oscillator, rational, Hulthén, Yukawa, logarithmic, power‐law, Morse potential as well as static and dynamic studies in molecules and atoms (including Rydberg states) and so forth .…”
