Abstract
The HFS-splitting of the 2s-2p and 3d-2p transitions of muonic arsenic and 3d-2p transitions of copper have been measured with high resolution Ge-semiconductor detectors to determine the nuclear quadrupole moments. A coincidence measurement was performed to separate the 2s-2p transition from the background. The nuclear spectroscopic quadrupole moments were found to be:Q spec=0.314(6) b for 7533 AsQ spec=0.220(15) b for 6329 Cu.
In addition, generalized Barrett moments were determined in a model-independent analysis of muonic transition energies.
