New shell model calculations for $^{40}Ar$ based on recent g-factor and lifetime measurements

We have redetermined the g factor and the lifetime of the 2 1 + state in 40Ar by applying the technique of alpha transfer from a carbon target to 36S beams in inverse kinematics combined with transient magnetic fields. In addition, the lifetimes of the 4 1 + and the 2 2 + states in 40Ar have been remeasured using the Doppler-shift-attenuation method (DSAM). Additional experimental details of the alpha-transfer measurements are provided. The results are discussed within the framework of new large-scale shell model calculations with both free and effective nucleon g factors
