“…The latter incorporate uncertainties of the fol- Table 2), (ii) peak-background separation -from 3% to 8% [for the 7~176 reaction with I~ = 0.7% (see Table 1)], (iii) abundance of the characteristic y-ray (17 in Table 1) in the decay scheme of the nucleus originating Table 3 compares them with our measurements at En= 14.5 MeV. There is an overall satisfactory agreement except for the 74Ge (n, ~)71Znm reaction for which the result of [18] exceeds by a factor of six the rest of entries. Among the more recent (n,p) measurements are those of Molla and Qaim [17] for 72Ge(n,p)V2Ga and 73Ge(n,p)Y3Ga at E n = 14.7 MeV.…”

Crosssections for 7~ (n, p) 7~ 7~ 2n)69Ge, 72Ge (n, c~)69Zn m and 74Ge(n, c~)71Znm reactions are measured in the energy range from 13.0 to 16.6 MeV by the activation method using Ge (Li) detector 7-ray spectroscopy and compared with predictions of the reaction model incorporating preequilibrium and equilibrium emission mechanisms to interpret the energy dependence of the isotopic effect occuring in the (n, p) reaction. The fitted single-particle state-density parameters g, determined here for the germaniums are discussed together with the g-values found previously for the Se, Zr and Pd isotopic chains. A validity of the consistency condition between the precompound and compound models, which relates g to the experimental level-density parameter a via a = gZg/6 is demonstrated. PACS: 25.40.Fq

Systematic experimental and theoretical investigations of the 72,73Ge(n,p)72,73 Ga and 72,74Ge(n,α)69,71Znm reaction cross sections are presented in the energy range from thresh- old to about 17 MeV neutron energy. The above reaction cross sections were measured from 8.8 to 11.4 MeV by using the activation method, relative to the 27Al(n,α)24Na refer- ence reaction. The quasi-monoenergetic neutron beams were produced via the 2H(d,n)3He reaction at the 5 MV VdG Tandem T11/25 accelerator of NCSR “Demokritos”. Statisti- cal model calculations using the code EMPIRE-II (version 2.19) taking into consideration pre-equilibrium emission were performed on the data measured in this work as well as on data reported in literature.

Abstract. The 72 Ge(n,α) 69m Zn, 74 Ge(n,α) 71m Zn, 76 Ge(n,2n) 75g+m Ge and 191 Ir(n,2n) 190 Ir g+m1 and 191 Ir(n,2n) 190 I rm2 reaction cross sections were measured from 9.6 to 11.4 MeV relative to the 27 Al(n,α) 24 Na reference reaction via the activation method. The quasi-monoenergetic neutron beams were produced via the 2 H(d,n) 3 He reaction at the 5 MV VdG Tandem T11/25 accelerator of NCSR "Demokritos". Statistical model calculations using the codes STAPRE-F and EMPIRE (version 2.19) and taking into account pre-equilibrium emission were performed on the data measured in this work as well as on data reported in literature.
