Absolute Cross Sections and Excitation Functions for (d, p) and (d, 2n) Reactions on

Abstract

Absolute cross sections and excitation functions for some (d,p) and (d,2n) reactions have been measured by activation and stacked-foil techniques. The cross sections for (d,p) reactions seem to indicate a direct mechanism, although there seems to be some compound nucleus admixture above the Coulomb barrier. A striking result is the great difference (a factor 3.5) between the (d,p) cross sections on the two Cu isotopes. This result is unexplained and requires confirmation. The (d,2n) reaction proceeds via compound-nucleus formation but the theoretical excitation functions, calculated on the basis of compound-nucleus formation followed by evaporation of particles, are not in agreement with the experimental ones. The isomeric ratio of the Zn 69 isomers is also discussed.

Proton and deuteron activation measurements at the NPI and future plans in SPIRAL2/NFS

“…8. that present data are in agreement with data Khandaher [5] and Tarkanyi [6], but Nassiff [8] and Gilly [17] experimental points are too high. Neither library agrees with the experimental data as in previous case.…”

“…Present data (Fig. 1) are in rough agreement with the data of Gilly [17] (they Similar case is 67 Ga production reaction (Fig. 2).…”

“…The present data are shown in Figs. 1-10 in comparison with EXFOR database [5][6][7][8][9][10][11][12][13][14][15][16][17] data and with evaluated data from the EAF 2007 [18] and TENDL 2014 [19] libraries. All evaluated data are corrected/normalized to the natural abundance of the sample.…”

Deuteron-induced reactions on manganese at low energies

“…II), are compared in Fig. 5 with the data formerly available up to 50 MeV [11,12,[47][48][49][50], the corresponding TENDL-2017 evaluation [15], and results of calculation using TALYS-1.9 code and its default input parameters [14]. The new measured data of 54,56 Mn activation are in agreement especially with the recent measurement of Tarkányi et al [12], extending to lowest energies the accurate experimental description.…”

Determination of 68Ga production parameters by different reactions using ALICE and TALYS codes

“…Gilly et al seems to be the only one to have studied 68 Zn(d, 2n) 68 Ga reaction. Their crosssection measured in the range of 5 to 12 MeV [12]. There is no data and excitation curve for 70 Zn(p, 3n) 68 Ga. Bonesso et al [13], Stelson and Mcgowan [14], Singh et al [15] and Bryant et al [16] have been working on 65 Cu(α, n) 68 Ga reaction below 30 MeV energy [13][14][15][16].…”
