Abstract
The hyperfine splitting of the 5g→4f transitions in muonic Re185,187 has been measured using high resolution high purity germanium detectors and compared to state-of-the-art atomic theoretical predictions. The spectroscopic quadrupole moment has been extracted using modern fitting procedures and compared to the values available in literature obtained from muonic x rays of natural rhenium. The extracted values of the nuclear spectroscopic quadrupole moment are 2.07(5) b and 1.94(5) b, respectively for Re185 and Re187.

F.W. has been supported by the German Research Foundation (DFG) under Project No. WA 4157/1. Most of the theory results in this article are part of the PhD thesis work of N.M., which was published at the Heidelberg University, Germany. The experiment was performed at the ?E1 beam line of PSI. We would like to thank the accelerator and support groups for the excellent conditions. Technical support by F. Barchetti, F. Burri, M. Meier, and A. Stoykov from PSI and B. Zehr from the IPP workshop at ETH Zurich is gratefully acknowledged. This work is part of a larger effort at the Paul Scherrer Institut towards the measurement of the nuclear charge radii of radioactive elements.
