Muonic x-ray measurements on the even-A gadolinium isotopes /sup 154/, /sup 156/, /sup 158/, and /sup 160/Gd have been made. The data have been analysed in a nearly model-independent manner to extract electric monopole and quadrupole moments for the low-lying states. The equivalent nuclear charge radii (Barrett radii) have been determined for the ground states with uncertainties of about 1 mfm. Extracted isotope shifts ..delta.. is greater than have been found to agree with electronic K/sub alpha/ x-ray measurements, but not with optical measurements. Normalized optical isotope shifts do agree. The isomer shifts of the 2/sub g//sup +/ states were measured directly from the muonic K x-rays. For /sup 158/Gd, disagreement with previous muonic x-ray measurements was found. Generalized quadrupole moments of the charge distribution as measured by muonic atoms have been determined and equivalent quadrupole radii for transitional quadrupole charge distributions of the 2/sub g//sup +/ states have been determined in conjuction with recent Coulomb excitation data. Pairing-Plus-Quadrupole (PPQ) Model calculations agree with extracted quadrupole moments using equal static and transitional quadrupole charge radii.
