Abstract	The authors report on a correlation experiment, where the spectra of neutrons and of the associated de-excitation gamma -rays, emitted after mu -capture in Ca, Tl, Pb, and Bi, were measured two- dimensionally. The neutron energy was determined directly using a gamma -n time-of-flight technique. Here, the gamma -rays provided time zero signals to start the time-of-flight measurement. In this way, the measurement was restricted to neutron transitions leading to excited final states. (7 refs).
