Experimental Studies of the Structure of $^{16}$C with Reactions at Intermediate Energy
Résumé
The possible existence of cluster structures in 16C has been investigated by inspecting their breakup (induced on CH2 targets) in 10Be+6He events. The excitation energy of the projectile nucleus prior to decay is obtained via an invariant mass analysis of identified fragments. The experiment has been carried out at the FRIBs facility of INFN-LNS, by using a fragmentation cocktail beam at intermediate energies (≈ 55 MeV/nucleon) and the CHIMERA 4π multi-detector. A non-vanishing yield in the 10Be+6He correlations is reported at an excitation energy of about 20.5 MeV in 16C, in analogy with previous works. To improve these results, we recently performed a new experiment by coupling CHIMERA and FARCOS at forward angles. Preliminary details of the new experiment are reported in the text.
