The ratio of muon-capture rate to beta-decay rate in the transitions 16O(0+: ground)↔16N(0-: 120 keV) is calculated with realistic nuclear models and with an exact formalism for lepton wave functions. In contrast to the results with no ground-state correlation, the calculated ratio is strongly reduced in agreement with the experimental data. Our results are compatible with the PCAC hypothesis. The effects of the exchange currents are found to be not large.
