Abstract

A comparative evaluation of two methods for the production of 172Tm in nuclear reactors is carried out. They are respectively based on two chains of double neutron capture reactions, 170Er(n,γ)171Er(n,γ)172Er(β)172Tm and 170Er(n,γ)171Er(β)171Tm(n,γ)172Tm, and a chain of triple neutron capture: 169Tm(n,γ)170Tm(n,γ)71Tm(n,γ)172Tm. Theoretical considerations with respect to both ways of production are formulated and the mathematical equation are solved. Experiments of irradiation of Er2O3 and Tm2O3 were performed. Advantages and drawbacks of both methods are discussed.
