The probabilities for non-radiative (n.r.) excitationsPn.r. in the muonic nuclides208Pb,232Th, and238U have been determined from (µ-,??)-measurements by comparing the intensities of muonic X-ray transitions in single and coincidence spectra. The value ofPn.r. (3p?1s), measured for the first time, is about 90% for the actinides232Th and238U, but only about 8% for208Pb. The value ofPn.r. (3d?1s) is found to be 10 % for233Th, 13% for238U, and about 4% for208Pb. For208Pb a vanishing strength of the n.r. decay of the 2p-level is found, while for232Th and for238U n.r. strengths of about 20% and 26%, respectively, are observed. By regarding two subcomplexes of the 2p?1s transitions leading to different mean excitation energies the n.r. transition probabilities were found to be different for238U only, 21.6% and 31.1.%, respectively. |
