Total reaction cross section and elastic scattering of 24.7 MeV alpha particles in the region of A = 60 nuclei

Nuclear model analysis of excitation functions of proton and deuteron induced reactions on 64 Zn and 3 He- and α-particle induced reactions on 59 Co leading to the formation of copper-61: Comparison of major production routes

“…The data by Sterns (1962) show an energy shift and low values till 30 MeV but look good thereafter. Budzanowski et al (1967) reported cross section only at 12.8 MeV and that measurement agrees within its uncertainty limits with other measurements. The data of Zhukova et al (1972) and Ansari et al (2004) are very low and show a shift in energy.…”

“…59 Co(α,2n) 61 Cu A number of groups measured the cross sections for production of 61 Cu through this reaction (Sterns, 1962;Budzanowski et al, 1967;Zhukova et al, 1972;Homma and Murakami, 1976;Michel and Brinkmann, 1980;Gadioli et al, 1984;Jastrzebski, et al, 1986;Levkovskij, 1991;Skulski et al, 1992;Singh et al, 1993;Szelecsényi et al, 2002;Ansari et al, 2004; see Table 1). All the experimental data are shown in Fig.…”

Mass and charge release by the evaporation of particles from compound nuclei around mass 60

“…In case of 3~176 reaction closed and open triangles, respectively do and do not take into account the symmetry of the input channel wave function ametrization was claimed to reproduce experimental values to within 35'; [16]. It was checked, that /m=-values thus obtained differ by no more than 1 unit from the more realistic optical-model results [5,6] for the 4He + 59Co reaction in the incident energy range investigated in this work.…”

“…Figure 1 presents examples of the excitation functions of the individual products of the 4He + 59Co reaction. For the purpose of this figure, all the cross sections measured in this work were normalized by equating the total reaction cross section to the values predicted by the optical model [5,6]. The data points from the earlier work [2,6] are also included in the figure.…”
