ATTEMPT TO ASSIGN NEUTRON RESONANCE SPINS IN 235U BY CAPTURE GAMMA RAY MULTIPLICITY MEASUREMENTS

摘要

An attempt has been made to assign neutron resonance spins in 235U by means of the multiplicity of radiative capture γ rays. The expected group¬ing of resonances according to spin was not observed, so spin assign¬ments were not possible. Arguments against further attempts at measure¬ment of the spin by indirect techniques are presented.
