Model-independent interpretation of the dynamic hyperfine effect in muonic atoms with an application toOs192 (original) (raw)
The Ford-%'ills-Barrett model-independent interpretation of muonic-atom transition energies is generalized to the dynamic hyperfine effect. Parameters necessary for the analysis of the most important case (quadrupole excitation by the 2p states) are calculated for all nuclei. These results are applied to new data for ' 'Os. The sign of the quadrupole moment of the first excited 2+ state is found to be negative; a previously reported measurement of its magnitude (-0.5 b) is inconsistent with the present experiment. Under the assumption that the transition charge is located near the nuclear surface, a new measurement of the quadrupole moment (Q, + =-1.0 b) is obtained. The equivalent quadrupole radius of the 0+~2+ transition is found to be 7.1 fm. NUCLFAB STRUCTURE Model-independent method for interpretation of dynamic hyperfine effect in muonic atoms.
