Abstract
Recoil of atoms following (n, gamma) reactions may cause them to desor b from the surface. This effect is studied in irradiation experiments under high thermal neutron flux for gold and iridium, utilizing prepac kaged ampules under vacuum. The role of thermal desorption is demonstr ated, through a comparative study of the behavior of different element s under identical conditions. Precise measurements of the populations of iridium isotopes were carried out, revealing large Ir-194/Ir-192 di fferentiation. This is shown to be related to the temporal history of desorption during the irradiation, and provides additional meaningful information about the process.
