Measurement of natW(p,xn)177,178,179Re excitation function of natural tungsten by using a 100-MeV proton beam

Abstract

Measurements of the proton-induced excitation function for the natW(p,xn)177,178,179Re nuclear reaction has been measured in the energy region below 100 MeV by using the 100-MeV proton linear accelerator at the Korea Multi-Purpose Accelerator Complex. The stacked foil activation technique was adopted in the present study. The gamma-rays generated from the proton-irradiated samples were measured by using a gamma-ray spectroscopy system with a HPGe detector. The 27Al(p,3p+n)24Na reaction was used as a monitor reaction for proton flux monitoring. The nuclear reactions of natW(p,xn)177,178,179Re were observed in the present study. The proton-induced excitation functions of natural tungsten were derived from the delayed gamma-ray yield of the produced nucleus. The present results were compared with the previous experimental excitation function data of Yu. E. Titarenko et al. [1].
