Abstract
Different excited states of \(^{13}\)C populated in the \(^{10}\)B + \(^{10}\)B reactions at a beam energy of 72.2 MeV were investigated. The study revealed both well-known and new, or infrequently populated states. In particular, the inclusive excitation energy spectra showed the presence of most of the states belonging to the K = 3/2\(^-\) rotational band that was proposed by several authors. Furthermore, a possibly new state at E\(_x\) = 19.0 MeV was strongly populated in the \(\alpha \) + \(^9\)Be coincidences. The measured state was found to have a well defined cluster structure. Additionally, so far unobserved \(\alpha \)-decay of the two rarely seen high-energy \(^{13}\)C states at 21.9 and 23.6 MeV is discussed.
