Abstract

The n decay of the giant-monopole-resonance region in

{}^{208}{Pb}

has been studied in an (

α, α^{'} n

) coincidence experiment at

E_{α} = 104

MeV. From the fast-neutron emission corresponding to the decay into the low lying single hole states in

{}^{207}{Pb}

a direct decay component of ≅15% was estimated for the resonant strength. In addition, evidence for a preequilibrium decay was found.
