Abstract
In this thesis, the build-up and decay of radioactivity in two stable isotopes of Bromine caused
by reaction with slow neutrons will be studied. In particular, we will be able to measure the
radioisotope capture cross section of these samples, using HPGe-detector and beta-counter on the
decay of radioactivity data taken. For the decay of Br-82 the ground state thermal neutron cross
section 0.2565±0.023barn by using High purified Germanium detector and for Br-80 decay the
ground state thermal neutron cross section 8.653±0.78barn by using beta counter were observed
from this work and the total thermal neutron cross section for the two isotopes obtained from the
measurement were compared with the calculated theoretical values
