Investigation of activation cross sections of proton induced reactions on rhodium up to 70 MeV for practical applications

TL;DR

This study measures proton-induced activation cross sections on rhodium up to 70 MeV, compares results with models, and discusses applications in medical isotope production.

Contribution

It provides new experimental excitation functions for various radionuclides and compares them with theoretical models, including some measurements reported for the first time.

Findings

New excitation functions for several radionuclides.

Comparison with theoretical nuclear models shows varying agreement.

Potential applications in medical isotope production are discussed.

Abstract

Excitation functions were measured for the production of the 101,100Pd, 102m, 102g,101m,101g,100,99m,99gRh and 97Ru radionuclides by bombardment of 103Rh targets with proton beams up to 70 MeV, some of them for the first time. The new results are compared with the earlier experimental data and with the theoretical nuclear model code calculations from ALICE-IPPE, EMPIRE and TALYS 1.6. Thick target yields were deduced and possible application of the new data for production of medically relevant 101m,101gRh and 97Ru are discussed.
