Abstract
Future facilities will allow the exploration of extremely neutron-rich
nuclei far from the valley of stability. It is discussed that the strong-neutron excess results in changes
in the collective excitations of such nuclei compared to
conventional stable nuclei. We propose muon capture as an experimental
tool to explore such changes. We will quantify our discussion by the
calculation of the total and differential muon capture rates on selected
calcium isotopes between 40Ca and 60Ca. Our calculations are
based on the random phase approximation and agree nicely with the
measured rates for 40Ca and 44Ca.
