Abstract

Abstract: A feasibility study of two-neutron transfer reactions, using 12 C and 19 F targets, was performed. In this experiment, a 6 He beam at 20 MeV incident energy was delivered by the RIBRAS facility. The main goal of this work was to test the RIBRAS system, operated in a single-solenoid mode, to investigate ( 6 He, α ) reactions in light nuclei. The excitation function of the 14 C nucleus, populated by the 12 C( 6 He, α ) reaction, was extracted from the data. Evidence of nn -transfer reactions populating the ground state and the first 0 1 + state in 14 C were observed. However, the present spectrum might have contribution from other reaction channels such as the 6 He breakup. Future experiments with the RIBRAS dual-solenoid mode will improve the quality of the data by reducing a significant amount of background.
