Muonic x-ray study of the charge distribution of /sup 144/ /sup 148/ /sup 150/ /sup 152/ and /sup 154/Sm. [Deformed Fermi distribution, transitions]
The measurement of the energies of the 4f ..-->.. 3d, 3d ..-->.. 2p, 2p ..-->.. 1s and, in the case of /sup 152/Sm, the 2s ..-->.. 2p muonic atomic transitions in separated isotopes of /sup 144/ /sup 148/ /sup 150/ /sup 152/ and /sup 154/Sm are reported. Using these transition energies as well as the hyperfine splittings of the 2p levels, the data were interpreted in terms of a deformed Fermi distribution for the charge density and obtained good fits. A model independent analysis of the isotope shifts in terms of generalized R/sub k/ moments was made and is in good agreement with electronic x-ray and optical isotope shifts. The static quadrupole moments and the isomer shifts of the first excited state of /sup 152/ and /sup 154/Sm were also determined from the 2p hyperfine structure. 54 references.
