Reaction (1) is the so-called neutronless or zero-neutron mode and has received special attention, particularly in light nuclei, where it has been used to identify the level A(Z-1)~xc as a giant resonance level '). The neutronless mode has been observed in intermediate and heavy nuclei using neutron detection or radiochemical t Research supported in part by the National Science Foundation under Grant GP-34527. * Present address: Varian Associates, Palo Alto, CA 94306, USA. 469

N2 - We have measured the energies and intensities of delayed γ-rays from 207,201Tl following muon capture on 207Pb. Probabilities for the emission of 0-6 neutrons have been deduced. Measured and predicted neutron multiplicities (based on an impulse approximation model) are in reasonable agreement for multiplicities of 2, 3, 4 and 5. Experimental values for high and low multiplicities are not accounted for by the theory. High angular momentum states involving the h 11 2 proton hole are observed in several of the thallium daughters. Using a simple shell-model approach, we have correlated μ-capture on the h 11 2 proton shell with the energy spectrum of directly emitted neutrons.
