One of the parameters is highly regarded nuclear physicist is the nuclear material cohesion. This parameter has a significant impact on the characteristics of the development of fission of heavy excited nuclei, Such that it can be impact on the fission, fission probability, possibility of isomer states and ... . The aim of this study change Am excited fission produced in the fusion process d 145Pu, is within the statistical model. Within this model, we calculated the probability of entering the leaflets containing nuclear isomer 145Am and calculates the probability of fission isotopes 139Am, 145Am, 141Am, 141Am to obtain information on nuclear material cohesion if Am. For this study, the first step we want t to calculate the Coulomb energy, surface tension and rotational fission barrier for estimate the fission barrier with a hump in drop model. Then, depending on experimental parameters fission barrier, we calculated barrier with two humps, and based on these, we estimate the numerical value of shell effects. The second step is to calculate the decay width through different channels and using Monte Carlo we estimate probability of fission isotopes 139Am, 145Am, 141Am, 141Am and 145Am likely to present leaflets nuclear isomer produced in the fusion process d 145Pu. Then with consider nuclear material cohesion as a free parameter, the possibility of entering isomer states are calculated and the data fit the theory with experimental data provides data on numerical value of nuclear material cohesion
