Different, complementary, techniques are used to experimentally probe clustering aspects in several carbon isotopes: C. Our approaches involve breakup reactions with radioactive cocktail beams (C), compound nucleus reactions and resonant scattering at low energies (C), and direct reactions with the detection of in-flight resonance decay fragments (C). In this paper, we discuss results of our experimental campaign: in C, we unveil the existence of a new excited state, characterized by clustering nature, at an excitation energy of 9.36 MeV (); the decay path of the Hoyle state in C (7.654 MeV, ) is investigated with unprecedented precision; we refine the spectroscopy of C above the -threshold supporting the possible appearance of the molecular bands, based on the Be structure, previously discussed in the literature; in C, we find evidence for He–Be decays. Our findings have an impact on the understanding of clustering phenomena in light nuclear systems.
