Lifetimes of short-lived excited states around the doubly-magic nucleus $^{48}$Ca have been measured using the Recoil Distance Doppler Shift method (RDDS) in combination with the CLARA and PRISMA spectrometers. This novel method allows to measure lifetimes of neutron-rich nuclei populated via multi-nucleon transfer reactions that were inaccessible before and it partially overcomes one of the limitations that the RDDS singles measurement presents, namely the side-feeding. Results from a recently performed experiment at LNL using a $^{48}$Ca beam onto a $^{208}$Pb target followed by a thick natural Mg degrader with the CLARA-PRISMA setup will be discussed.
