Seminar topic: “Phenomenological model for description of fission cross sections of heavy nuclei in high energy region”

Speaker: V. I. Yurevich

Abstract:

A phenomenological model for approximation and numerical estimation of fission cross sections was developed for interactions of high-energy nucleons with heavy nuclei. The model predictions of fission cross sections are compared with the most reliable experimental data, available estimations and recent theoretical results for different nuclei from ¹⁸¹Ta to ²³⁹Pu. The model well reproduces the experimental results above 30 MeV for actinides and above 50 MeV for pre-actinides and it has good prediction potential.
