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

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.
