Description

An ongoing experiment at PSI aims to determine the nuclear charge radius of $^{226}$Ra - needed by an experiment aiming at measuring atomic parity violation in a radium ion - by means of muonic atom spectroscopy. An intermediate test was performed with a $^{185,187}$Re target which is the last stable element whose nuclear charge radius has not been measured and shows similar nuclear structure effects as radium. In $^{185,187}$Re there exists an intermediate domain of energy states in which the quadrupole splitting is proportional to the spectroscopic quadrupole moment. In this contribution, the analysis of the $5g\rightarrow 4f$ hyperfine transitions in muonic $^{185,187}$Re for the extraction of its spectroscopic quadrupole moment is presented.
