Empirical formula on (n,3He) reaction cross sections at 14.6 MeV neutrons

The systematic behavior of the cross sections of (n,(3)He) nuclear reactions has been studied by various researches at neutron energy of 14.6MeV. A new empirical formula based on the Q-value dependence of the cross sections of the investigated reaction has been proposed. The cross sections obtained from the new formula are compared with the other proposed formulae results and the experimental data. It seems that the present formula based on the Q-value dependence provides the good description for cross sections of neutron-induced (n,(3)He) nuclear reactions at 14.6MeV.

New empirical formulae for (n,t) cross sections at 14.6 MeV

The aim of the present work is to develop simple empirical formulae based on the Q-value dependence of the nuclear reaction for estimating the (n,t) cross sections at energies near 14.6MeV. The (n,t) cross sections are analyzed in terms of the compound nucleus model. The empirical formulae based on the compound nucleus model are obtained giving the cross section in terms of the investigated reaction Q-values instead of the widely used asymmetry parameter. In addition, the new formulae include two fitting parameters on even-A and odd-A target nuclei with 27 ≤A≤ 204. The cross section results obtained with the present formulae are compared with the experimental data. Finally, the new formulae compared with the literature data give a good fit in calculating the (n,t) reaction cross sections at energies near 14.6MeV.

Investigating the (p,n) excitation functions on 104–106,108,110 Pd isotopes

Palladium is known to play an important role in cold nuclear fusion technology because of hydrogen storage characteristics. In this paper, the excitation functions of 104Pd (p,n)104Ag, 105Pd (p,n)105Ag, 106Pd (p,n)106Ag, 108Pd (p,n)108Ag and 110Pd (p,n)110Ag nuclear reactions were calculated for proton energies up to 20MeV. Contribution of various level density models on the calculations of (p,n) excitation functions was investigated using the nuclear theory codes such as TALYS 1.6 and ALICE/ASH. A comparison of the predicted and measured cross section data was also presented.

Analysis of(n,p)cross sections near 14 MeV

The present work aims to obtain new empirical formulae for calculating the cross sections of (n,p) reactions. The systematic behaviour of the (n,p) cross sections has been studied on 112 target nuclei with 4 ≤ Z ≤ 94 in energy range of 14-15 MeV. The new formulae compared with the literature data give a good fit in calculating the (n,p) reaction cross sections at neutron energies near 14 MeV. Thus, accurate predictions of unmeasured cross sections for the considered reaction channel can be provided with the present paper.

Analysis of cross sections of (n,t) nuclear reaction using different empirical formulae and level density models

This paper aims the calculations of cross section of the 27Al(n,t)25Mg, 50Cr(n,t)48V, 56Fe(n,t)54Mn, 58Ni(n,t)56Co, 64Zn(n,t)62Cu, 70Ge(n,t)68Ga, 92Mo(n,t)90Nb, 106Cd(n,t)104Ag and 114Cd(n,t)112Ag nuclear reactions. These cross section calculations were obtained using the different level density models in ALICE/ASH code. Besides, the cross sections of the investigated reactions at incident energies near 14.6 MeV were predicted by using the empirical formulae suggested in our previous paper and in the literature. Therefore, the predicted nuclear data are compared with the other data taken from the literature.

A review of (n,p) and (n,α) nuclear cross sections on palladium nuclei using different level density models and empirical formulas

The critical works about nuclear science and technology depend on nuclear data. Cross section data of (n,p) and (n,α) reactions on 102,105,106,108,110Pd isotopes were calculated for projectile energies from threshold to 20 MeV. Here, the effects on nuclear excitation functions of different level density models were studied using ALICE/ASH and TALYS 1.6 computer codes. Besides, for (n,p) and (n,α) reactions in energy range of 14-15 MeV, numerous empirical formulas, obtained by various authors, were also used for predicting the cross sections. Hence, a comparison of the simulation results and experimental values was presented together with the data calculated by the empirical formulas.
