$(\alpha,n)$ reactions are needed to model a wide range of physical process ranging from the amount of neutrons available for the astrophysical $s$-process to the neutron energy spectrum emitted from radioactive fuel storage containers. Yet the cross sections of these reactions often have large, or worse yet uncharacterized, uncertainties that result in inconsistency between model and direct...

In this work the experimental and theoretical study of 6Li, 10C + 58Ni systems is presented. On one hand, 6Li is a stable weakly bound nucleus, its α + d break-up threshold is 1.47 MeV. On the other hand, 10C is an unstable nucleus with excess of protons and can break into three possible channels: 2p + 8Be, with binding energy of 3.820 MeV, 9B + p with binding energy of 4.006 MeV; and 6Be + α...

The poor knowledge of the $\alpha$-nuclear potential in unstable nuclei still dominates the uncertainties associated to the production of the heavy p-nuclei [1,2]. Calculations of the elastic scattering cross section at energies close to the Coulomb barrier based on global $\alpha$-nucleus potentials differ up to a factor of 2 when moving towards unstable nuclei with higher proton-to-neutron...
