Abstract
The exothermic neutron capture reaction n+ 32 He→p+ 31 H has recently been used to deposit a well known energy in liquid 32 He. In this paper we describe calculations of the distribution of the energy deposited in the interaction region resulting from such capture reactions in liquid 32 He. This calculation is of interest in the interpretation of the low temperature experiments to simulate cosmic string formation in the early Universe. In addition we calculate the fraction of the energy which is absorbed by interactions with atomic electrons compared to the total, including non ionising mechanisms (the so-called Lindhard factors).
