Abstract

Experiments have been performed on the formation of bromine and rhodium isomers, by thermal as well as resonance neutrons, in order to study capture levels. With slow neutrons of variable energies obtained from a Ra-Be source in a slowing-down medium of paraffin, we have studied: (a) the relative formation of the isomeric pairs as a function of the distance from the source and (b) the migration distances for each isomer.
