Cross section measurements for production of some therapeutic radionuclides using d(Be)-breakup neutrons

摘要

This report describes cross section measurements of (n,p) reactions relevant to the production of ~(64)Cu, ~(67)Cu and ~(89)Sr in a fast neutron field, generated via break-up of 14 MeV deuterons on a thick Be target. Work on the ~(153)Eu(n,p) ~(153)Sm reaction is in progress. The neutron spectrum characterization was done via multiple foil activation and spectrum unfolding via the iterative code SULSA. The measured integral cross section data have been compared with values calculated from the spectral neutron distribution and known excitation functions. It is postulated that at an intense fast spectral neutron source, e.g. a spallation source, it would be advantageous to use an (n,p) reaction for the production of therapeutic radionuclides.
