Figure 1 . Energy spectrum for different states as a function of the screening parameter.
The plot of the energy spectrum is shown in Fig.1 for the ground, first excited and second excited states as a function of the screening parameter for a fixed values of the potential parameters and . It can be observed that the energy levels of the ground, first excited and second excited states decrease as the screening parameter is increased. In Fig.2, we displayed the behaviour of the wave function of the Screened Kratzer potential for different eigenstates. For the parameters , as it increase, their nodes get steeper. For the variation of , the converse is the case. It is also observed that for the wavefunction for the first excited state decreased first and then rose steeply for the variation of . This steepness happened gradually for .
