The excitation function for (�,xn) reactions from 20 to 80 MeV on Tantalum have been calculated using TALYS-1.2 nuclear model code involving the fixed set of global parameters. Level density parameter is varied to get good agreement between the calculated and measured data with minimum effort on parameter fitting. This is of importance required for the validation of nuclear model approaches with increased predictive power. The alpha induced cross-sections provide clues to the problem of nuclear structure and offer the testing ground for ideas about nuclear forces. Accurate knowledge of crosssection in alpha induced reaction at energy levels where resonance occurs is crucial while designing nuclear reactors.

Systematic measurements of nuclear reaction cross sections were done in the low energy range for the two reactions 45Sc(d,p)46Sc and 45Sc(α,n)48V. Thin foils of high-purity (99.95%) natural Sc targets (100% 45Sc), purchased from Good-Fellow, were irradiated with 10 and 20 MeV incident deuteron and α-particle energies, respectively, at beam current of 100 nA using MGC-20 cyclotron. For precise measurements, high-purity Ti and Cu foils were used for monitoring the actual deuteron and α-particle beam intensities, respectively. The conventional stacked-foil technique was applied for measurement and calculation of the cross section values using a high-resolution γ-ray spectrometer for measuring the radioactivity. Nuclear model code EMPIRE-3.2 was used for calculation of the investigated excitation functions. The obtained results were compared with the experimental values and TENDEL-2021 data which are based on TALYS-1.96 code calculations. The integrated yields for the two reactions, bas...

Investigations of the natTi(p,x)43,44m,44g,46,47,48Sc,48V nuclear processes up to 40MeV
Applied Radiation and Isotopes, 2009
Independent and cumulative production cross-sections for the nat Ti(p,x) 48 V, 43,44m,44g,46,47,48 Sc nuclear processes are reported here, for the energy region of 4-38 MeV by using a stacked-foil activation technique. Measured data were critically compared with the earlier reported values, and also with the theoretical data from the TALYS and ALICE-IPPE codes. The measured nat Ti(p,x) 48 V reaction is important for charged particle beam monitoring purposes, whereas the 43,44,47 Sc radionuclide have various practical applications in nuclear medicine.

In the frame of a systematic study of charged particle production routes of medically relevant radionuclei, the excitation function for indirect production of (178m)Ta through (nat)Hf(α,xn)(178)W-(178m)Ta nuclear reaction was measured for the first time up to 40 MeV. In parallel, the side reactions (nat)Hf(α,x)(179,177,176,175)W, (183,182,178g,177,176,175)Ta, (179m,177m,175)Hf were also assessed. Stacked foil irradiation technique and γ-ray spectrometry were used. New experimental cross section data for the (nat)Ta(d,xn)(178)W reaction are also reported up to 40 MeV. The measured excitation functions are compared with the results of the ALICE-IPPE, and EMPIRE nuclear reaction model codes and with the TALYS 1.4 based data in the TENDL-2013 library. The thick target yields were deduced and compared with yields of other charged particle ((p,4n), (d,5n) and ((3)He,x)) production routes for (178)W.

Tm is a candidate radioisotope for both nuclear medicine diagnostics and therapy due to its emitted Auger-electrons, low energy X-and gamma-rays. In the frame of a systematic study of excitation functions for production of medically relevant radioisotopes by charged particle induced reactions on rare earths, the 165 Ho(a,2n) 167 Tm reaction and the 165 Ho(a,n) 168 Tm, 165 Ho(a,3n) 166 Tm, 165 Ho(a,4n) 165 Tm side reactions were measured up to 40 MeV by the stacked foil irradiation technique and gamma-ray spectroscopy. The measured results were compared to the ALICE-IPPE and EMPIRE-II theoretical curves. Thick target yields, impurity levels and specific activities were deduced and compared with the same parameters for other charged particle production routes of 167 Tm.

The excitation function of the natCu(3He,x)65Zn nuclear reaction was measured from its threshold up to 53 MeV incident energy relative to the natTi(3He,x)48V monitor reaction by using the conventional stacked foil activation technique combined with HPGe γ-ray spectrometry.
