Excitation functions of 93Nb(p,x) reactions from threshold to 42.5 MeV

Abstract

The excitation functions of 93Nb(p,x) reactions from their respective thresholds to 42.5 MeV were measured at the MC-50 cyclotron of Korea Institute of Radiological and Medical Sciences by using the stacked-foil activation and off-line γ-ray spectrometric technique. The thick target integral yields for the formation of the investigated radionuclides from the respective thresholds to 42.5 MeV were deduced based on the measured cross sections data. The 93Nb(p,x) reactions cross sections obtained in the present work were compared with the literature data and theoretical values based on the TENDL-2015 data library. The production cross sections of the investigated radionuclides (e.g. 88,89Zr, 87,88Y, 90Nb) are applicable in research, medical diagnosis and radiotherapy. The present data provide information’s, which will support in testing and understanding the nuclear reaction models.
