Systematics of ground-state quadrupole moments of odd-A deformed nuclei determined with muonic M x rays
The ground-state quadrupole moments of /sup 151/Eu, /sup 153/Eu, /sup 159/Tb, /sup 163/Dy, /sup 167/Er, /sup 177/Hf, /sup 179/Hf, /sup 191/Ir, and /sup 193/Ir were determined by measuring the quadrupole hyperfine-splitting energies of muonic M x rays. The results are Q = 0.903(10) e b for /sup 151/Eu, Q = 2.412(21) e b for /sup 153/Eu, Q = 1.432(8) e b for /sup 159/Tb, Q = 2.648(21) e b for /sup 163/Dy, Q = 3.565(29) e b for /sup 167/Er, Q = 3.365(29) e b for /sup 177/Hf, Q = 3.793(33) e b for /sup 179/Hf, Q = 0.816(9) e b for /sup 191/Ir, and Q = 0.751(9) e b for /sup 193/Ir. The present quadrupole moments, compared with values obtained from electronic-atom hyperfine measurements, show that the Sternheimer correction factors used in the rare-earth electronic-atom analysis are unreliable. Systematics of deformation parameters ..beta../sub 2/ calculated from the present quadrupole moments for odd-A nuclei, and from B(E2) values of Coulomb excitation measurements for even-A nuclei, also indicate that the largest deformation change so far known exists between /sup 151/Eu and /sup 153/Eu. Except at the onset of nuclear deformation, the deformation parameters of the odd-A nuclei are quite consistent with those of the even-A neighbors.
