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. [...]

We report on an attempt to reproduce the observation of $\beta^-$-delayed proton emission from $^{11}$Be through detection of the final state nucleus $^{10}$Be with accelerator mass spectrometry. Twelve samples were collected at the ISOLDE facility at CERN at different separator settings, allowing tests of different sources of contamination to be carried out. [...]

$^{11}$Be($\beta$p), a quasi-free neutron decay?
/ Riisager, K. (Aarhus U.) ; Forstner, O. (Vienna U. ; Stefan Meyer Inst. Subatomare Phys.) ; Borge, M.J.G. (CERN ; Madrid, Inst. Estructura Materia) ; Briz, J.A. (Madrid, Inst.

Estructura Materia ; CERN) ; Heinz, A. (Chalmers U. Tech.) et al.
We have observed $\beta$-delayed proton emission from the neutron-rich nucleus $^{11}$Be by analysing a sample collected at the ISOLDE facility at CERN with accelerator mass spectrometry (AMS). With a branching ratio of (8.4 $\pm$ 0.6)$\times$ 10$^{-6}$ the strength of this decay mode, as measured by the B$_\mathrm{GT}$-value, is unexpectedly high. [...]

We have observed beta+-delayed alpha and p-alpha emission from the proton-rich nucleus 21Mg produced at the ISOLDE facility at CERN. The assignments were cross-checked with a time distribution analysis. [...]

Beta-delayed proton emission from $^{21}$Mg

(Aarhus U.) ; Jonson, B. (Goteborg, ITP) ; Laursen, K.L. (Aarhus U.) ; Nilsson, T. (Goteborg, ITP) ; Perea, A. (Madrid, Inst. Estructura Materia) et al.
Beta-delayed proton emission from $^{21}$Mg has been measured at ISOLDE, CERN, with a detection setup including particle identification capabilities. $\beta$-delayed protons with center of mass energies between 0.39$\,$MeV and 7.2$\,$MeV were measured and used to determine the half life of $^{21}$Mg as $118.6\pm 0.5\,$ms.
