  We study total muon capture rates in light nuclei, taking into account
renormalizations of the nuclear vector and axial vector strengths. We estimate
the influence in the results of uncertainties of the spin-isospin interaction
parameter and nuclear densities. A few of these reactions are theoretical
benchmarks for physics involving searches for neutrino oscillations. New
experiments in muon capture in several targets are suggested, in the light of
some discrepancies with theory, crudeness of some experimental results and
relevance to neutrino physics.
