Abstract

The magnetic field generated by a bound muon in heavy muonic atoms results in an induced nuclear magnetic dipole moment even for otherwise spinless nuclei. This dipole moment interacts with the muon, altering the binding energy of the muonic state. We investigate the relation of this simple, semi-classical-insriped approach to nuclear polarisation (NP) calculations. Motivated by the relative closeness of this simple estimate to evaluations of NP, we extract effective values for the nuclear magnetic polarisability, a quantity otherwise unknown, and put forward a simple back-of-the-envelope way to estimate the magnetic part of NP.
