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 × 1^0–2μ²_N and B(M1;5/2⁺ → 3/2⁺_g.s.) = 7.12^+1.27_–0.96 × 10^–2μ²_N. 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.
