A consistent framework for the calculations of all muoncapture
processes on the deuteron, 3He, and other light nuclei
should be ultimately prepared. This requires that the initial and
final nuclear states are calculated with the same Hamiltonian
and that the weak current operator is “compatible” with the
nuclear forces. If the results of such calculations can be
compared with precise experimental data, our understanding
of muon capture (and other) important weak reactions will be
definitely improved.
