Sažetak
The structure of neutron-rich beryllium isotopes has been investigated using different heavy-ion induced transfer reactions. A strong sensitivity to the chosen core nucleus is found for the cores of 9Be and 10Be, respectively. With a 9Be core, molecular rotational bands up to high excitation energies are observed due to the pronounced 2alpha-cluster structure, whereas only few states at low excitation energies are populated with a 10Be core. For 11Be a detailed investigation has been performed for the three states at 3.41 MeV, 3.89 MeV and 3.96 MeV, which resulted in the most probable spin-parity assignments 3/2+, 5/2- and 3/2-, respectively. Furthermore we have studied particle-hole states of 16C using the 13C(12C, 9C)16C reaction and found 14 previously unknow states.
