Yields and Recoil Properties of Products from the Interaction of Natural Copper with Intermediate-Energy ¹⁴N, ¹⁵N and ⁴⁰Ar Ions

Abstract

Heavy-ion nuclear reaction / Copper / Intermediate energy / Formation cross section / Recoil range / MultitracerAbstract Reaction residues in the interaction of copper with intermediateenergy 14 N, 15 N and 40 Ar ions (26 to 135 MeV/u) have been studied using non-destructive y-ray spectrometry. Formation cross-sections and average forward ranges were measured for 58 products. The data were used to obtain the mass yield distribution and the longitudinal momentum transfer. The results are compared with those from the studies reported on the interaction of copper with heavy projectiles, and discussed in terms of the transition of the reaction mechanism from low energy to relativistic energy.

Radiochemical study on the mechanism of target fragmentation of Cu, Nb, Pr and Au targets induced by 12C and 40Ar projectiles

“…An example of the measured momentum is demonstrated in Fig. 2 as a function of projectile energy in MeV/u together with the data which were obtained in the experiment for the projectile energies less than 150 MeV/u by using heavy ions from RIKEN Ring Cyclotron [14]. It shows that the momentum converges to the same value as the projectile energy increases irrespective of the entrance nuclear system.…”

Simultaneous production of 28Mg and 47Ca by high-energy heavy-ion irradiation for applications in biology

“…Taniguchi et al reported that the cross section for the production of 28 Mg in the interaction of Cu with the beam of 14 N (134.3 MeV/nucleon) and 15 N (69.2 MeV/nucleon) was 0.68 mb and 0.57 mb, respectively [19]. The results indicate that the energy dependence of the cross section is small in the energy region studied, when we can assume there is no effect of mass between 14 N and 15 N. The cross section for the formation of 28 Mg in the reaction of Fe with Production yields of 28 Mg and 47 C were also summarized in Table 1.…”
