Spallation neutron emission spectra in medium and heavy target nuclei by a proton beam up to 140MeV energy

Cross sections of neutron-induced reactions

“…These can also be used for performing Hauser-Feshbach [24] calculations with Monte Carlo simulations [25] to estimate the cross sections for neutron induced fission [26], evaporation residues, or evaporation neutron multiplicities [27] and for comparison of the photon [26,27] versus nucleon induced fission as well. Moreover, the neutron-scattering cross sections are very important for reactor physics calculations [1][2][3][4][5][6][7] of the ADSS applications.…”

“…Recently, the accelerator-driven subcritical systems (ADSS) and their neutronics have been studied by many researchers [1][2][3][4][5][6]. The subcritical reactor is driven critically by spallation neutrons produced by bombarding a high-energy proton beam with high current (greater than ∼10 mA) [7] on a heavy element target.…”

Theoretical Production of Radiopharmaceuticals Used in Mycardial Perfusion Scintigraphy

“…Nuclear reactions induced by incident intermediate and high energy protons are very important because of wide range of technical applications [1]. Nowadays, lots of radioisotopes are used in medical applications.…”

Investigation of the neutron emission spectra of some deformed nuclei for (n,xn) reactions up to 26 MeV energy

“…Up to now, numerous equilibrium and preequilibrium reaction model calculations carried out with updated computer codes. Lately, equilibrium and pre-equilibrium reaction model calculations for neutron emission spectra produced by (p,xn) [14,15], (n,xn) [16,17] reactions and for neutron (or charged paticle) induced reactions cross sections [18][19][20] on some targets have been carried out by many researchers. In the present paper, by using equilibrium and preequilibrium reaction mechanisms, the (n,xn) reaction neutron-emission spectra for some deformed target nuclei as 165 Ho, 181 Ta, 184 W, 232 Th and 238 U were investigated up to 26 MeV incident neutron energy.…”
