Analytical method for estimation isotope yield under photonuclear production
The heuristic model for description space-energy characteristics of the high-energy bremsstrahlung has been developed. On its basis the method for analytical estimation photonuclear yield of isotopes in wide range of atomic number (Z=20-80) and size of a target as well as of the electron energy (40…...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The heuristic model for description space-energy characteristics of the high-energy bremsstrahlung has been developed. On its basis the method for analytical estimation photonuclear yield of isotopes in wide range of atomic number (Z=20-80) and size of a target as well as of the electron energy (40…100 MeV) is proposed. The analysis of validity of the model assumptions has been executed by means of it comparison with the results of simulation using the program package PENELOPE/2006 [1] supplemented with database on the cross-sections of photonuclear reactions. It has been shown earlier that such simulation method provides close fit with the experimental results. As an example the reactions of practical interest 48Ti(γ,p)47Sc, 68Zn(γ,p)67Cu and 187Re(γ,n)186Re are presented. |
