The finite size of the carbon nucleus causes the Korbit muon density within the nucleus to be smaller than the density for a point nucleus. Previously calculated muon capture rates in carbon should be reduced by about 6% for this effect. Our recalculated capture rate to the ground state of B/sup 12/ does not differ greatly from previously calculated values. It is 7300 sec-t, with an assigned theoretical error of about 10%. The result tends to support the Feynman-Gell-Mann proposal of a conserved vector current in the framework of a universal Fermi interaction, We give also various predicted correlation coefficients, which do not differ significantly from those of Wolfenstein. The allowed and all second-forbidden matrix elements were calculated as a function of the intermediate coupling parameter a/K, The beta-decay rate of B/sup 12/ is predicted correctly for a/K = 4.5, a value which is close to that favored by other evidence. The calculated secondforbidden vector matrix element differs by 20% from the "experimental" value derived from a magnetic dipole transition rate in Ct/sup 2/
