ResumoWe report the measurement of the energies of 4f → 3d, 3d → 2p and 2p → 1s muonic atomic transitions in 161Dy. The energies have been interpreted in terms of a nuclear charge density which is a five-parameter generalized Fermi distribution. Band mixing effects were taken into account when interpreting the hyperfine structure (h.f.s.). Using the muonic 3d h.f.s. we determined the ground-state spectroscopic quadrupole moment to be 2.468 ± 0.029 e · b. The quadrupole static moments of the first two excited nuclear states of the ground-state band and the transition moments connecting these states to the ground state were determined relative to the ground-state moment by using the muonic 2p h.f.s. The ground-state intrinsic hexadecapole moment was found to be 1.2±0.5 e· b2 using the 3d h.f.s.
