Title: Analog B ( M 1 ) strengths in the T z = ± 3 2 mirror nuclei Mn 47 and Ti 47

Abstract

The lifetimes of the first excited $$\frac{7}{2}$$ states in the Tz = ±$$\frac{3}{2}$$ mirror nuclei 47Mn and 47Ti 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 analogue M1 strengths in mirror nuclei. The two analogue 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 analogue B(M1) strengths.
