Abstract
The measurement of thermal neutron cross sections gives basic information about the
internal structure of atomic nuclei and their structure. Measurement of Thermal Neutron
cross-section of Sb -121 has been performed at the Addis Ababa University Nuclear
physics Laboratory using the concept of neutron activation Analysis. Irradiations without
Cadinium cover were performed and the neutron transmission through the cover was
calculated. High resolution gamma ray spectrometry measurements was undertaken in
order to check the consistency of the results. The thermal neutron cross section measured
for Sb-121 using slow neutrons is ( 5.450.23b). The results are discussed and
compared with previous Measurement. In general there is good agreement between the
observed and calculated value of thermal neutron capture cross section.
