The lifetimes of the first excited states of the N=30 isotones 50Ca and 51Sc and the Z=18 isotopes 44-46Ar isotopes have been determined using a novel technique that combines the Recoil Distance Doppler Shift method with the CLARA-PRISMA spectrometers in multinucleon transfer reactions. The results allow determinination of the effective charges above 48Ca and test the strength of the N=28 magic number when moving away from the stability line.

Abstract
The lifetimes of the first excited states of the N=30 isotones 50Ca and 51Sc and the Z=18 isotopes 44-46Ar isotopes have been determined using a novel technique that combines the Recoil Distance Doppler Shift method with the CLARA-PRISMA spectrometers in multinucleon transfer reactions. The results allow determinination of the effective charges above 48Ca and test the strength of the N=28 magic number when moving away from the stability line.
