/ Diget, C Aa (Aarhus U.) ; Barker, F C (Australian Natl. U., Canberra) ; Borge, M J G (Madrid, Inst. Estructura Materia) ; Cederkäll, J (CERN) ; Fedosseev, V N (CERN) ; Fraile, L M (CERN) ; Fulton, B R (York U., England) ; Fynbo, H O U (Aarhus U.) ; Jeppesen, H B (Aarhus U.) ; Jonson, B (Goteborg, ITP) et al.
The β -delayed triple- α particle decay of 12 B has been measured with a setup that favours coincidence detection. A broad state in 12 C, previously reported around 10 MeV, has been seen and its properties determined through R-matrix analysis of the excitation spectrum. [...]

News on $\beta$-delayed particle emission from $^{14}$Be
/ ISOLDE Collaboration
$\beta$-delayed charged particles from $^{14}$Be have been measured and give an upper limit on $\beta$-delayed $\alpha$-particles of B($\beta\alpha$) < $\,6.7\times\!10^{-5}$ and a tentative branching ratio on $\beta$-delayed tritons of $7.5\times\!10^{-5}$ < B($\beta$t) < $\,3.9\times\!10^{-4}$. We combine the knowledge on $\beta$-delayed particles from $^{14}$Be to deduce information on the $\beta$-strength distribution..

Study of beta-delayed 3-body and 5-body breakup channels observed in the decay of $^{11}$Li
/ Madurga, M. (Madrid, Inst. Estructura Materia) ; Borge, M.J.G. (Madrid, Inst. Estructura Materia) ; Angelique, J.C. (Caen U.) ; Bao, L. (Chalmers U. Tech.) ; Bergmann, U. (CERN) ; Buta, A.

The beta-delayed charged particle emission from ^11Li has been studied with emphasis on the three-body n+alpha+^6He and five-body 2alpha+3n channels from the 10.59 and 18.15 MeV states in ^11Be. Monte Carlo simulations using an R-matrix formalism lead to the conclusion that the ^AHe resonance states play a significant role in the break-up of these states. [...]

Clarification of the Three-Body Decay of 12C (12.71 MeV)
/ Fynbo, H O U (Aarhus U.) ; Prezado, Y (Instituto Estructura de la Materia, CSIC, Serrano, Madrid, Spain) ; Bergmann, U C (CERN) ; García-Borge, M J (Instituto Estructura de la Materia, CSIC, Serrano, Madrid, Spain) ; Dendooven, P (Univ. of Jyväskylä, Finland) ; Huang, W X (Univ. of Jyväskylä, Finland) ; Huikari, J (Univ. of Jyväskylä, Finland) ; Jeppesen, H B (Univ. of Aarhus, Denmark) ; Jones, P (Univ. of Jyväskylä, Finland) ; Jonson, B (Chalmers Tekniska Högskola och Göteborgs Univ., Sweden) et al.
Using β decays of a clean source of 12 N produced at the IGISOL facility, we have measured the breakup of the 12 C (12.71 MeV) state into three α particles with a segmented particle detector setup. The high quality of the data permits solving the question of the breakup mechanism of the 12.71 MeV state, a longstanding problem in few-body nuclear physics. [...]

The $\beta$-decay of $^{9}$Li to the high lying states in $^{9}$Be
/ Prezado, Y ; Bergmann, U C ; García-Borge, M J ; Cerdekall, J ; Fraile-Prieto, L M ; Fynbo, H O U ; Jeppesen, H B ; Jonson, B ; Meister, M ; Nilsson, T et al.
Mirror $\beta$-transitions should have similar strengths as long as binding energy, Coulomb energy and other explicitly breaking effects are small. However, large $\beta$-decay asymmetries have been observed in the decay of $^{9}$C "Phys. [...]

Asymmetry in the super-allowed $\beta$-transitions of the A=9 isobars
/ García-Borge, M J ; Prezado, Y ; Bergmann, U C ; Boutami, R ; Cederkäll, J ; Diget, C A ; Fraile-Prieto, L M ; Fynbo, H O U ; Jading, Y ; Jeppesen, H B et al.
We report here on the recent $\beta$-decay studies of the A = 9 isobar made at ISOLDE/CERN. Mirror $\beta$ - transitions in the A=9 chain are compared and a large asymmetry factor is deduced for the transitions to high excitation energy in $^{9}$Be (11.8 MeV) and $^{9}$B (12.2 MeV) fed in the $\beta$-decay of $^{9}$Li and $^{9}$C respectively.

New information on the $\beta$-decay of $^{11}$Li from Doppler broadened $\gamma$-lines

The $\gamma$-ray spectrum following $\beta$-decay of $^{11}$Li has been remeasured at the ISOLDE facility at CERN. Two new transitions were observed through the use of large Ge-detectors. [...]
