Clustering in \({}^{11,12,13}\)C

Le résumé fourni par la source

Characterization of the excited states of 11C, 12C, 13C isotopes was performed using experimental data collected at the INFN-LNL in Italy. The study employed a 95 MeV 14N beam on 10B targets to probe clustering phenomena in carbon isotopes. The experimental setup included a detector system covering polar angles from 15◦ to 72◦, enabling the study of reactions with two and three products in the exit channel. Analysis of the three-product exit channels is presented to provide insight into the process of analyzing such reactions. Presented results for the 7Be+4He, 8Be+4He, and 9Be + 4He decays of 11C, 12C, 13C, respectively, unveil states at 7.6, 9.7, and 14.1 MeV in 12C, 8.1 and 8.4 MeV in 11C, as well as a broad peak centered at 13.6 MeV with a possible contribution of states from 13.4 to 14.1 MeV in 13C. The detection of these states serves as a crucial validation of the analysis and data selection procedures, representing an initial step before exploring other exit channels.
