Measurement of the quadrupole moment of 185Re and 187Re from the hyperfine structure of muonic X rays

ATOMIC PHYSICS 185,187Re, 208Pb(μ-, μ-'), E at 29 MeV/c, [negative muon beam from the decay of pions produced in C(p, π), E=590 MeV]; measured Eγ, Iγ, energy and intensities of muonic x-rays using two HPGe detectors at the HIPA facility of Paul Scherrer Institut; deduced hyperfine splitting of the 5g to 4f muonic atom transitions, and compared to state-of-the-art atomic theoretical predictions; extracted spectroscopic quadrupole moments for ground states of 185Re and 187Re.

NUCLEAR MOMENTS 185,187Re; measured muonic atom hyperfine structure; deduced spectroscopic quadrupole moments of ground states. Comparison with previous experimental measurement using natural Re target, and with theoretical predictions.
