Abstract

Measurement was conducted at the INFN-LNL, employing a Tandem accelerator to achieve a 95 MeV 14N beam focused on 10B target (201 µg/cm²) with the aim to explore the cluster structures of light carbon isotopes. The main focus of this report will be on the 13C nucleus. Data were collected with a six-telescope detection system that allowed for the observation of many-body exit channels. Here are presented some results of the data analysis for the excited states of 13C from reactions with two and three products in the exit channel. In the 10B(14N,11C)13C reaction, well-defined peaks were identified at 2.0, 3.7, 5.7, 7.4, 9.4, 11.7, 13.9, and 15.9 MeV. The states from ground state to 5.7 MeV are well understood and are used to correct the spectrum, while more states can contribute to the states at higher excitations and further investigation is needed. In the 10B(14N,11C9Be)4He channel, states were identified at 13.1, 13.9, 15.6, and 18.5 MeV. The experimental results show consistency with the previously published data, supporting theoretical models of clustering and molecular-like structures in 13C. Further analysis of other reaction channels and states will be presented in future publications, aiming to enhance our understanding of multi-center clustering in carbon isotopes.
