Study of muonic atoms in the A = 40 - 70 and A = 100 - 130 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, November 15, 1978-December 1, 1979
During the reporting period the muonic x-ray measurements on /sup 106/ /sup 108/ /sup 110/ /sup 111/ /sup 112/ /sup 113/ /sup 114/ /sup 116/Cd and /sup 122/ /sup 124/ /sup 125/ /sup 126/ /sup 128/ /sup 130/Te have been completed and the data were analyzed in terms of effective Barrett charge radii. The muonic x-ray spectra of /sup 154/ /sup 155/ /sup 156/ /sup 157/ /sup 158/Gd have been measured with high precision. Special methods were developed to extract isotopically clean spectra from the measurements with the separated Gd target which contained large amounts of isotopic impurities. The even-A Gd spectra have been analyzed in terms of nuclear monopole and quadrupole parameters and isomer shifts. Additional studies of the nuclear polarization corrections in muonic /sup 208/Pb have been made. The isomer shift of the excited 2/sup +/ state of /sup 204/Pb has been measured: ..delta..E/sub iso/ = 1.98 +- 0.16 keV. The transfer of muons stopped in liquid hydrogen to Au nuclei contained in thin foils (30 ..mu..g/cm/sup 2/) that are suspended in the liquid hydrogen has been observed. About 20 times more muonic Au atoms were produced in this LH/sub 2/-Au arrangement as compared to a solid Au target of the same mass.
