Abstract

The neutron decay of the isoscalar giant monopole resonance (GMR) and of the underlying continuum in 124Sn was studied. The GMR decay mechanism is shown to be a function of the excitation energy. The non-statistical decay component decreases with excitation from (20±5)% in the lower part to (10±5)% in the higher part. For the lower part there is evidence for pre-equilibrium decay. The decay of the continuum also shows a non-statistical decay component.
