N2 - The lifetimes of the first excited 72- states in the Tz=±32 mirror nuclei Mn47 and Ti47 have been extracted utilizing the γ-ray line shape method, giving τ=687(36) ps and τ=331(15) ps respectively. Since these transitions are essentially pure M1 transitions, these results allow for a high-precision comparison of analog M1 strengths in mirror nuclei. The two analog B(M1)s are observed to be identical to a precision of about 10%. The expected dependence of the transition matrix element with Tz has been used to extract the separate isoscalar and isovector components of the transition strength, and the results are discussed in the context of predictions, based on the isospin formalism, regarding analog B(M1) strengths.
