Study of muonic atoms in the A = 100 - 140 mass regions (nuclear charge radii, isotope and isotone shifts) and in the Sm-Gd and W-Os-Pt transition regions (electric monopole and quadrupole moments). Progress report No. 6, October 16, 1980-October 15, 1981
During the reporting period the analysis of the over 100 muonic spectra of practically all stable isotopes of Ru, Pd, Cd, Sn, Te and Ba has progressed satisfactorily and systematic trends of the ..delta..N = 2 isotope and of the ..delta..Z = 2 isotone shifts have been established. The analysis of the muonic x-ray spectra of the Gd-isotopes /sup 154/ /sup 155/ /sup 156/ /sup 157/ /sup 158/ /sup 160/Gd has been completed. A paper describing precise measurements of the ground-state quadrupole moments of /sup 155/Gd and /sup 157/Gd has been published. The discrepancies in the energy splitting of the 3d and 2p levels of muonic /sup 208/Pb was partly solved by a precise re-measurement of the d/sub 5/3/ - d/sub 3/2/ splitting energy. Uncertainties in the nuclear polarization corrections cannot account for the discrepancies that still exist in the 2p/sub 3/2/ - 2p/sub 1/2/ splitting energy. A theoretical attempt to explain the observed isotope shifts in Ca nuclei was qualitatively successful. A refinement of the model, however, is needed to provide a quantitative explanation of the experimental results.
