Tech.) ; Borge, MJ (Madrid, Inst. Estructura Materia) et al.
The $^{8}$B+$^{64}$Zn reaction at 38.5 MeV has been studied at HIE-ISOLDE CERN to investigate proton halo effect on the reaction dynamics. For the first time it was used the only existing post-accelerated $^{8}$B beam. [...]

The experiments to determine the electron capture and $\beta$-decay of $^8$B into the highly excited states of $^8$Be
/ Vinals, S (Madrid, Inst. Estructura Materia) ; Borge, M J G (Madrid, Inst. Estructura Materia) ; Tengblad, O (Madrid, Inst. Estructura Materia) ; Nacher, E (Valencia U., IFIC) ; Benito, J (UCM, Madrid, Dept. Phys.) ; Figuera, P (INFN, Catania) ; Fraile, L M (UCM, Madrid, Dept. Phys.) ; Fynbo, H O U (Aarhus U.) ; Gad, A (Aarhus U.) ; Jensen, J (Aarhus U.) et al.
The main goal of this work is to study the structure of the highest energy states in $^8$Be populated following the $\beta^+$-decay and the electron capture (EC) of $^8$B. With this aim, two experiments were performed at ISOLDE-CERN in 2017 and 2018. [...]

Study of the scattering of $^{15}$C at energies around the Coulomb barrier

The neutron rich carbon isotope $^{15}$C is the only known case of an almost "pure" 2s$_{1/2}$ single-neutron halo ground state configuration. At collision energies around the Coulomb barrier the reaction dynamics is expected to be dominated by single neutron transfer and breakup [...]

Probing proton halo effects in the $^8$B+$^{64}$Zn collision around the Coulomb barrier
/ Spartà, R (Catania U. ; INFN, Catania) ; Di Pietro, A (INFN, Catania) ; Figuera, P (INFN, Catania) ; Tengblad, O (CSIC, Madrid) ; Moro, A M (Seville U.) ; Martel, I (Huelva U.) ; Fernández-García, J P (Seville U.) ; Lei, Jin (INFN, Pisa) ; Acosta, L (Mexico U. ; INFN, Catania) ; Borge, M J (CSIC, Madrid) et al.
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 distribution, especially in the Coulomb-nuclear interference region.

First Accurate Normalization of the $\beta$-delayed $\alpha$ Decay of $^{16}$N and Implications for the $^{12}$C$(\alpha,\gamma)^{16}$O Astrophysical Reaction Rate
/ Kirsebom, O.S. (Aarhus U.) ; Tengblad, O. (CSIC, Madrid) ; Lica, R. (CERN ; Bucharest, IFIN-HH) ; Munch, M. (Aarhus U.) ; Riisager, K. (Aarhus U.) ; Fynbo, H.O.U. (Aarhus U.) ; Borge, M.J.G. (CSIC, Madrid ; CERN) ; Madurga, M. (CERN) ; Marroquin, I. (CSIC, Madrid) ; Andreyev, A.N. (York U., England) et al.
The $^{12}\text{C}(\alpha,\gamma){}^{16}\text{O}$ reaction plays a central role in astrophysics, but its cross section at energies relevant for astrophysical applications is only poorly constrained by laboratory data. The reduced $\alpha$ width, $\gamma_{11}$, of the bound $1^-$ level in $^{16}$O is particularly important to determine the cross section. [...]
