Characteristic analysis for a TiT target using nuclear reactions

It is found that the T-3(p,n)He-3 reaction changes the concentration profil e of a TiT thin film, which is a MeV neutron target, owing to proton irradi ation of a few coulomb. The concentrations in the TiT thin film, including the areal densities of Ti and T, were estimated by using several analytical methods, such as He Rutherford backscattering, proton Rutherford backscatt ering, and elastic recoil detection time of flight, and by measuring total neutron cross-sections of C-12 and O-16 before and after T-3(p,n)He-3 react ion. The respective areal densities of T and Ti in the TiT thin film were 3 .8 x 10(18) particles/cm(2) and 1.3 x 10(19) particles/cm(2) after several T-3(p,n)He-3 reactions, and these values, which were obtained by several an alytical methods, coincided within 5%. These results were compared with the data provided by the target-producing company.
