Multinucleon transfer reactions were employed in a series of experiments at Legnaro National Laboratories of INFN and at the Tandem Laboratory of the Horia Hulubei National Institute in Bucharest. The main aim was to investigate the shape coexistence phenomenon in even–even Sn isotopes, with mass A = 112–118, through lifetime measurements of excited 0+ states. Recent Monte Carlo Shell Model (MCSM) calculations predict, in fact, the appearance of well-separated secondary minima in the potential energy surfaces of these Sn isotopes, corresponding to deformed, prolate configurations. In this contribution, details on the analysis procedure and preliminary results are discussed.
