Firstly, the solvability of some quantum models like Eckart and
Rosen?Morse II are explained on the basis of the shape invariance
theory. Then, two generalized types of the Klauder?Perelomov and
Gazeau?Klauder coherent states are calculated for the models. By
means of calculating the Mandel parameter, it is shown that the
weight distribution function of the first type coherent states
obeys the Poissonian and super-Poissonian statistics, however, the
weight distribution function of the second type coherent states
obeys the Poissonian and sub-Poissonian statistics.
