Abstract
Muonic x-ray spectra have been measured for and . From the data we have determined model-independent charge radii and isomer shifts of certain excited nuclear states and have inferred spectroscopic quadrupole moments of excited states for both isotopes. The quadrupole moment of the lowest state in is found to be positive, in agreement with previous muonic-atom data but in disagreement with a recent Mössbauer study. values of low-lying excited states have been determined for . An muonic-nuclear resonance has been discovered in .
NUCLEAR STRUCTURE ; measured muonic x-ray spectra; deduced monopole and quadrupole charge parameters, isomer shifts.
