Abstract :
Recent results on shell evolution in light exotic nuclei obtained through experiments performed at GANIL using the MUST2 particle array are reported. The one-nucleon transfer reactions 20O(d,t) was investigated using a setup combining the MUST2 and TIARA particle arrays, together with EXOGAM germanium detectors. Preliminary results on the populated states as well as comparison with calculated spectroscopic factors are presented. In a second study, the Z=8 shell closure was investigated by means of the two-neutron transfer reaction 14O(p,t) using a set of MUST2 telescopes. A newly observed state at low excitation energy in the unbound 12O points to the Z=8 shell quenching, analogously to the established case at N=8 in the neutron-rich mirror nucleus 12Be.
