“…It results in a broadening of the angular distribution with decreasing bombarding energy (cf Figure 12). The angular distributions also become pro gressively smoother (12,44,216) as the energy and the degree of kinematical mismatch are increased, finally approaching exponentially fo rward-rising distribu tions. Examples for this behavior are presented in Figure 13, where, among others, the angular distributions of damped one-proton transfer processes for the reaction 40Ca + 4 0 Ca (1 1) are shown.…”

“…At is a parameter that describes the effect: of the tangential friction. 61 Ar is the product of the tangential component of the friction tensor and an effect:i ve path length of interaction, the path lengths implied by Ar in MeV between 20° and 40°). This trend, however, is not observed.…”

Collisions of 16 0 ions on targets of 94 2 197A 208Pb, and 232 111. . d • .d r, u, are 1nvest1gate at mc1 ent energies of 140 and 315 MeV, and compared to published data on peripheral collisions at 33.6 GeV. At 140 MeV, the isotope-production cross sections resemble the ground-state Q-value systematics characteristic of a partially-equilibrated, di-nuclear system formed in deeply-inelastic scattering. The yields are independent of shell and pairing effects in the target and residual nuclei. These Q-value systematics fail at 315 MeV, where the relative element yields are similar to those at 33.6 GeV. A theory of projectile fragmentation accounts for. .

“…The concept of nuclear friction represents the energy loss of a projectile as it traverses a nucleus. In models of nuclear friction, this energy dissipation is proportional to the overlap of the nuclei and the relative radial velocity [41][42][43], both of which are significantly lower in peripheral collisions.…”

Neutron transfer in the C13+Au197 reaction from gold isotope residuals

Residual gold nuclei were produced via neutron transfer at multiple energies using a 130 MeV 13 C beam incident on a stacked foil target consisting of alternating layers of 197 Au and 27 Al. Production cross sections, over an energy range of 56 to 129 MeV, for seven gold isotopes and two gold isomers were determined through activation analysis. By using the Wilczyński binary transfer model with a modified version of the recoil formula and a standard evaporation model, we were able to reproduce the isotopic production cross sections at high beam energy, with some disagreement at lower beam energies. This limiting angular momentum model does not predict the transfer of sufficient angular momentum to reproduce the observed isomeric populations.
