A direct measurement of the decay width of the excited 0_1^+ state of ^6Li using the relative self-absorption technique is reported. Our value of Γ_γ,0_1^+→1_1^+=8.17(14)_stat.(11)_syst. eV provides sufficiently low experimental uncertainties to test modern theories of nuclear forces. The corresponding transition rate is compared to the results of ab initio calculations based on chiral effective field theory that take into account contributions to the magnetic dipole operator beyond leading order. This enables
