The behavior of reaction cross section with proton projectiles on different isotopes of molybdenum to produce technetium

Abstract

In the present study the behaviour of reaction cross section of Technetium production with protons as projectile on different stable isotopes of Molybdenum with its importance had been studied. The theoretical reaction cross-section calculation had been done by using COMPLET computer code based on the compound nucleus and pre-equilibrium nuclear reaction stages. The result have been compared with experimental data to check its quality. The evaluation has been done for some selected reaction channels of 95 42Mo(p,n)95 43T c, 96 42Mo(p,n)96 43T c, 97 42Mo(p,2n)96 43T c, 98 42Mo(p,3n)96 43T c and 100 42 Mo(p,2n)99 43T c in the incident proton energy range from 10 MeV up to 30 MeV by using 95 42Mo, 96 42Mo, 97 42Mo, 98 42Mo and 100 42 Mo Molybdenum isotopes as a target nucleus. As a result calculated reaction cross sections is higher in case of 100 42 Mo and reaction channel 100 42 Mo(p,2n)99 43T c comparatively. This indicates, production of Technetium is better in these isotope and reaction channel. The probability of production of Technetium is dependent of the incident proton energy and comparatively at lower energy region the dominance of compound nucleus reaction stage has been seen. But at higher energy region it is dominated by pre-equilibrium reaction stage. Also the result of calculated reaction cross section by COMPLET code is closer to experimental data that is obtained from EXFOR Library with variation of less than 10% in most reaction channels. All the above results obtained from the study had been analyzed and presented in tabular and graphical form in relation to proton kinetic energy.
