Abstract

All cross sections of proton induced reactions, angular distributions, energy spectra and double differential cross sections of neutron, proton, deuteron, triton, helium and alpha-particle emissions for p+ 204,206,207,208 Pb, 209 Bi reactions are consistently calculated and analyzed at incident proton energies below 200 MeV. The optical model, the distorted wave Born approximation theory, the unified Hauser-Feshbach and exciton model which includes the improved Iwamoto-Harada model are used. Theoretically calculated results are compared with the existing experimental data.

Highlights

New accelerator-driven technology that utilizes spallations, such as the production of tritium and the transmutation of radioactive waste, is a growing interest in such type of reactions especially due to the emerging new ideas concerning the hybrid systems
The Accelerator-Driven System (ADS) requires nuclear data of common cross sections and especially the data of neutron and proton induced energy-angle correlated spectra of secondary light particles as well as double differential cross sections to model the performance of the target/blanket assembly and to predict neutron production, activation, heating, shielding requirements, and material damage
The optical potential parameters for proton are obtained from the experimental data of total reaction cross section and elastic scattering angular distributions for p+208Pb and 209Bi reactions at incident proton energy up to 250 MeV

Summary

Introduction

New accelerator-driven technology that utilizes spallations, such as the production of tritium and the transmutation of radioactive waste, is a growing interest in such type of reactions especially due to the emerging new ideas concerning the hybrid systems. Such systems are supposed to use intense high-energy proton beams, which induce spallation reactions on heavy targets. The Accelerator-Driven System (ADS) requires nuclear data of common cross sections and especially the data of neutron and proton induced energy-angle correlated spectra of secondary light particles as well as double differential cross sections to model the performance of the target/blanket assembly and to predict neutron production, activation, heating, shielding requirements, and material damage.
