Abstract

Interactions of tetraneutrons, which are assumed to be produced in the nuclear fission process, with nuclei are studied in the framework of optical and Hauser-Feshbach statistical models. It predicts a large probability of 89Sr production for the tetraneutron-induced reaction on 88Sr compared to other isotopes. The same technique is applied to the tetraneutron-induced reaction on 27Al and the hexaneutron-induced reaction on natural zinc to revisit two historical multi-neutron experiments performed in the past.
