The energies of muonic x-ray transitions sensitive to the nuclear charge parameters have been measured with a precision up to 9 ppm in muonic /sup 90/Zr. Combining our muonic-atom results for the equivalent nuclear charge radii R/sub k/,..cap alpha.. with recent elastic electron scattering data, the rms radius of /sup 90/Zr could be determined as /sup 1/2/ = 4.2726(9) fm. In addition to the nuclear monopole charge distribution, nuclear polarization correlations between the muonic 1s and 2s and the 1s and the two 2p states could be determined. With additional constraints from elastic electron scattering and theory, the nuclear polarization corrections of the four lowest-lying states could be evaluated with precisions of the order of 15%. Of particular significance is the result for the two 2p states, because the experimentally determined 2p/sub 1/2/ correction is smaller than the nuclear polarization correction in the 2p/sub 3/2/ state, in contrast to current theoretical models.
