We studied transition rates for the lowest 1/2+ and 5/2+ excited states of 17C through lifetime measurements with the GRETINA array using the recoil-distance method. The present measurements provide a model-independent determination of transition strengths giving the values of B(M1;1/2+ → 3/2+g.s.) = 1.04+0.03–0.12 × 10–2μ2N and B(M1;5/2+ → 3/2+g.s.) = 7.12+1.27–0.96 × 10–2μ2N. The quenched M1 transition strength for the 1/2+ → 3/2+g.s. transition, with respect to the 5/2+ → 3/2+g.s. transition, has been confirmed with greater precision. Furthermore, the current data are compared to importance-truncated no-core shell model calculations addressing effects due to continuum and three-body forces.
