Excitation functions of proton induced nuclear reactions on natural copper using a medium-sized cyclotron

Abstract

SummaryActivation techniques have been used to measure the excitation functions of proton induced nuclear reactions on natural copper from their thresholds up to 27.5 MeV. The beam current was measured using a Faraday cup with secondary electron suppression, and the radioactivity of the products was determined

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

“…The measured excitation function presented in Fig. 3 is in good agreement with the literature data [10,[15][16][17]23,38,43] as well as the theoretical results extracted from TENDL-2013 library. However, the data measured by Medows [7] are significantly higher around proton energy of 33-40 MeV and the data reported by Williams et al [28] are significantly lower than the present and literature data as well as the theoretical results extracted from TENDL-2013 library.…”

“…1 that the present excitation function is similar to that of IAEA recommended data [11]. Other literature data [7][8][9]12,13,[18][19][20][23][24][25]38] are lower than the values of IAEA recommended data [11] and higher than the theoretical data of the TENDL-2013 library [46]. However, the data reported by Ghosal [6] at proton energies above 27 MeV and by Levkovskij [16] at below 25 MeV are higher than the IAEA recommended data [11] and the theoretical data based on the TENDL-2013 library [46].…”

“…The measured excitation function of 62 Zn is shown in Fig. 1 together with the available literature data [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] and the theoretical data extracted from the TENDL-2013 library. Our results are slightly lower than the IAEA recommended data [11] but higher than those from the TENDL-2013 library [46].…”

Activation cross-section measurements of some proton induced reactions on Ni, Co and Mo for proton activation analysis (PAA) purposes

“…To confirm the cyclotron beam intensity and energy, a thin copper monitor foil (50 µm) of high-purity 99.999%, supplied by Goodfellow, Cambridge, UK, was placed in front of the stack [16]. This Cu foil was irradiated simultaneously with the main target foils and then analyzed with the same gamma ray spectrometer in a comparable geometry.…”

Medical Radioisotopes Production: A Comprehensive Cross-Section Study for the Production of Mo and Tc Radioisotopes Via Proton Induced Nuclear Reactions on natMo

“…To confirm the cyclotron beam intensity and energy, a thin copper monitor foil (50 m) was placed in the front of the stack (Al-Saleh, et al, 2006). Copper is an ideal target material with respect to its availability, physical, mechanical and chemical properties to be used in monitoring process.…”
