Measurements of 14 mev neutron activation cross sections

Radiochemical Study of 45Sc(n,p)45Ca and 89Y(n,p)89Sr Reactions in the Neutron Energy Range of 13.9 to 14.7 MeV

“…Via non-destructive y-ray spectrometry using decay data of "Y as: low-level ß~ counting (at Jülich). The results are given in Tables 1 and 2. The '"Sc(n,a)'*^K reaction cross sections measured in this work agree, within the limits of errors, with the data of Bayhurst et al [3], Ikeda et al [11] and Pepelnik et al [12], and also fit into the excitation function reported by Bostan and Qaim [6]. Similarly the present ''Y(n,2n)'^Y reaction cross-section data fit well in the excitation function reported by Klopries et al [7], which is based on a large number of literature values.…”

Gross Section Measurements for (n,d*), (n,t) and (n,n′α) Reactions at 14 MeV

“…gamma-ray intensity abundance of the target nuclide mass of sample _ counting correction factor time intervals from the end of the Irradiation to the Start and fmish of counting, respectively atomic weight measured full-energy peak area total correction factor of the activity The cross sections measured in the present work are summarized in Table 2. They are compared with the values given in the literature [1][2][3][4][5][6][9][10][11][12][13][14][15][16][17][18][19][20], To date comprehensive studies for (n,d*), (n,t) and (n,n'a) reactions had been carried out at Jülich [1 -6]. In those publications, for medium and heavy-mass nuclei with Z > 22 the (n,d*), (n,t) and (n,n'a) cross section at 14 MeV appears to be related to the neutron excess {N-Z)/A of the target nucleus.…”
