Abstract

A study has been made of the interaction between an ultraweak flux of thermal neutrons (I n=20 n/s·cm2) and a copper cathode during electrolysis in a 1M solution of KOH in H2O. An effect involving the generation of appreciable elastic and plastic deformations, revealed as transverse bending of the copper plate and damage to its surface, was observed in the copper. It was shown that the average cross section for absorption of thermal neutrons in the copper is increased approximately twenty times compared with its equilibrium value.
