We have investigated the K and L transitions in the muonic spectra of Bi 209 and of the separated isotopes Pb 206 , Pb 207 , and Pb 208 , using a Ge(Li) spectrometer. Our isotope shifts in Pb, in excellent agreement with the optical data, are half those predicted by the A llz law. The agreement between our shifts and the optical shifts strongly suggests the absence of nuclear polarization by the muon. We have studied the M\. and E2 hyperfine (hf) interactions in Bi 209 . The Ml results, although not sensitive enough to distinguish models of nuclear magnetization distributions, rule out a point magnetic dipole. The E2 constants, when used in conjunction with the measured isotone shift between Bi 209 and Pb 208 , suggest a quadrupole distribution produced by an /z 9/2 proton and a slightly (~1%) deformed Pb 208 core. We have examined the effects of E3 mixing of Bi 209 nuclear levels on the K and L intensity ratios and on the interpretation of the hf constants.

“…It has also been assumed that the initial massive leptons (μ~, e~) are unpolarized and that the spin of the final massive leptons is unobserved. These processes are analyzed in Culligan et al (1961), Uberall (1961, Lundy et al (1962), Winston (1963, and Galindo and Pascual (1968b). (74) ].…”
