| dc.description.abstract | This work uses two independent neutron removal reactions to investigate nuclear states relevant for two contexts: the 30P(p; )31S resonance reaction, which plays a crucial role in nucleosynthesis pathways in novae, and the neutrinoless double beta decay (0 ) of 136Xe ! 136Ba. To achieve these objectives, high-resolution measurements using the 32S(d; t) and the 137Ba(3He; ) reactions were employed to probe excitation energies of interest in 31S and 136Ba, respectively. Both experiments were performed using the Q3D spectrograph at the Maier-Leibnitz Laboratory (MLL) in Garching, Germany. A rigorous statistical analysis of the 32S(d; t) data was used to resolve a discrepancy concerning the existence of an astrophysically relevant state in 31S at around 6.4 MeV. The analysis of the second dataset provided valuable spectroscopic information to test calculated matrix elements for 136Xe 0 . | |
