The anomaly in lithium abundance is a well-known unresolved problem in nuclear astrophysics. A recent revisit to the problem tried the avenue of resonance enhancement to account for the primordial ^{7}Li abundance in standard big-bang nucleosynthesis

Proton halo effects in the 8B+64Zn reaction at an energy around 1.5 times the Coulomb barrier have been studied at HIE-ISOLDE CERN using, for the first time, the only existing postaccelerated 8B beam. This, together with the use of a high granularity

We report the first detection of the second-forbidden, nonunique, 2+→0+, ground-state transition in the β decay of F20. A low-energy, mass-separated F+20 beam produced at the IGISOL facility in Jyvaskyla, Finland, was implanted in a thin carbon fo

Near Coulomb Barrier Scattering of $$^{15}$$ 15 C on $$^{208}$$ 208 Pb

In the last years, the neutron rich carbon isotope \(^{15}\)C has been debated as a halo nucleus (\(S_n=\) 1215 keV, \(S_{2n}=9395\) keV) according to reaction experiments at high energies [1]. If so, it would be the only halo nucleus exhibiting a pu
