On transfer reactions playing a role in fission and in heavy-ion physics

TL;DR

This paper explores the similarity in transfer reactions during fission and heavy-ion collisions, suggesting a common nucleon transfer law and comparable transfer times of about 0.17 yoctoseconds.

Contribution

It proposes that nucleon transfer laws are consistent across fission and heavy-ion reactions, with implications for understanding transfer times.

Findings

Cross section curves resemble neutron number distributions in fission.

Isotopic cross sections follow Gaussian distribution laws.

Transfer times are estimated to be around 0.17 yoctoseconds.

Abstract

The cross section curves for the formation, at the barrier, of trans-target isotopes of a heavy element by bombardment of a heavy target with various heavy ions are shown to be similar to the distribution of the neutron number N of a fission fragment around its most probable value . Moreover the isotopic cross sections for one-, two- and three- proton transfer products are found to be in agreement with the Gaussian distribution law of the atomic number Z of a fission product around its most probable value . This situation suggests that the law of transfer of nucleons could be the same in fission and in particular heavy-ion reactions, and that the transfer time could be the same, i.e. of the order of 0.17 yoctosecond.
