Abstract
In the present research, we want to simulate the fission process of the excited nucleus 207At produced in fusion reaction 19F+188Os in the framework of the modified statistical model with considering the effects of projection of spin about the symmetry axis, K, and temperature. In our simulation, we calculate the fission cross section and anisotropy of the fission fragment angular distribution for 207At and by fitting the calculated data with the experimental data extract the magnitude of the temperature coefficient of the effective potential,, and the scaling factor of the fission-barrier height,. Furthermore, we show that the appropriate values of these parameters for 207At are and .Then, in order to show that the ability of this model to estimate another features of fission process, we calculate for example neutron multiplicity by using the extracted parameters for the excited nucleus 207At. And also, we show that the calculated data for the neutron multiplicity for the excited nucleus 207At are satisfactorily in agreement with the experimental data.
