Finite Distributions of NuclearM1andE2Moments in MuonicIn115,Cs133, andPr141

The distributions of nuclear $M1\mathrm{}$ and $E2\mathrm{}$ moments in the nuclei ${}_{}{}^{115}{}_{}{}^{}\mathrm{In}$, ${}_{}{}^{133}{}_{}{}^{}\mathrm{Cs}$, and ${}_{}{}^{141}{}_{}{}^{}\mathrm{Pr}$ have been investigated by observing the hfs of their muonic x-ray spectra. The $M1\mathrm{}$ hfs interaction constants are in good agreement with the values calculated from the configuration-mixing model. The measured $E2\mathrm{}$ hfs constant in the $2p_{\frac{3}{2}}$ state of muonic ${}_{}{}^{115}{}_{}{}^{}\mathrm{In}$ is in agreement with theory only if the free-atom value for the spectroscopic quadrupole moment is corrected for atomic polarization effects.
