Excitation functions of proton induced nuclear reactions on natW up to 40MeV

Abstract

Excitation functions for the production of the 181,182m,182g,183,184g,186 Re and 183,184 Ta radionuclides from proton bombardment on natural tungsten were measured using the stacked-foil Re has remarkable applications in the field of nuclear medicine, whereas the data of 183,184g Re and 183 Ta have potential applications in thin layer activation analysis and biomedical tracer studies, respectively.

Evaluation of charged particle induced reaction cross section data for production of the important therapeutic radionuclide186Re

“…The normalized data were about 5% lower than the nuclear model calculations while the general trend of the excitation function followed the nuclear theory. Recently, Khandaker et al [24] reported data for the same reaction up to 40 MeV. The estimated uncertainties were between 8 and 14%.…”

“…Pement 24 Na monitor reactions were used with a good status of reaction cross sections. The uncertainty in the absolute cross section values was 12%; near the threshold it was about 20%.…”

Measurement of excitation functions in proton induced reactions on natural copper from their threshold to 43MeV

“…The experimental technique and the data evaluation procedure were similar as described in the previous works [48,49]. The established stacked-foil activation and off-line c-ray spectrometric technique was used to determine the production cross-sections of the residual radionuclides from a proton irradiation on natural copper.…”

Excitation functions and yields for cyclotron production of radiorheniumvianatW(p,ߙxn)181-186gRe nuclear reactions and tests on the production of186gRe using enriched186W

“…Recently a critical evaluation of the existing data was done using extensive nuclear model calculations by Hussain et al [9]. Besides pointing out many discrepancies in the data [2,[10][11][12][13][14][15][16][17], it was concluded that the use of highly enriched 186 W target material is absolutely necessary to produce high-purity 186g Re via the 186 W( p, n)-reaction, and that the energy of protons should be < 18 MeV [9].…”
