The g factor of the first 2+ state of 54Cr was remeasured employing the combined technique of projectile Coulomb excitation in inverse kinematics and transient magnetic fields. The value obtained, g=+0.840(56), is significantly larger than previous data. The new value agrees better with a truncated than with a large-scale shell model calculation. The present result is discussed in the context of recently determined g factors of the first 2+ states of 50Cr and 52Cr as well as B(E2) values determined from lifetime measurements.
