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 and large solid angle detection system, allowed for a careful mapping of the elastic angular...

We examine the results on the determination of the Coulomb-free $^{1}S_0$ proton–proton (p–p) scattering length by analyzing the cross section of the quasi-free p + d $\rightarrow $ p + p + n reaction at center-of-mass energies below 1 MeV. This was achieved using a Bayesian data-fitting approach, yielding a p–p scattering length $a_{pp} =...
