Activation cross-section measurements for producing short-lived nuclei with 14MeV neutrons—Ge, Pd, Yb

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 ^{102,105,106,108,110}Pd 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.

Neutron activation cross-sections for Ytterbium isotopes at (14.6±0.3)MeV

The cross-sections of (nat)Yb (n,x)(172,173) Tm, (174)Yb(n,p) (174) Tm, (174)Yb (n,α) (171)Er, (176)Yb(n,p) (176) Tm, (176)Yb(n,α)(173) Er, and (176) Yb(n,n')(176m)Yb have been measured at 14.6±0.3MeV neutron energy, among them two cross-sections (nat)Yb (n,x)(172,173)Tm are reported for the first time. These experimental cross-sections are compared with experimental data found in the literature, with evaluated nuclear data in JENDL-4.0 and TENDL-2010 libraries and with theoretically calculated values based on nuclear reaction modular codes EMPIRE-3.0 and TALYS-1.2.
