The excited states of unstable $^{20}$O were investigated via $\gamma$-ray spectroscopy following the $^{19}$O$(d,p)^{20}$O reaction at 8 $A$MeV. By exploiting the Doppler Shift Attenuation Method, the lifetime of the 2$^+_2$ and 3$^+_1$ states were firmly established. [...]

Intruder configurations in $^{29}$Ne at the transition into the island of inversion: Detailed structure study of $^{28}$Ne
/ Wang, H. (RIKEN (main)) ; Yasuda, M. (Tokyo Inst. Tech.) ; Kondo, Y. (Tokyo Inst. Tech.) ; Nakamura, T. (Tokyo Inst. Tech.) ; Tostevin, J.A. (Tokyo Inst. Tech. ; Surrey U.) ; Ogata, K.

(JAEA, Ibaraki) et al.
Detailed $\gamma$-ray spectroscopy of the exotic neon isotope $^{28}$Ne has been performed for the first time using the one-neutron removal reaction from $^{29}$Ne on a liquid hydrogen target at 240~MeV/nucleon. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $^{28}$Ne and the negative-parity states are identified for the first time.

Study of multi-neutron emission in the $\beta$-decay of $^{11}$Li
/ Delaunay, F. (Caen U.) ; Achouri, N.L. (Caen U.) ; Algora, A. (Valencia U., IFIC) ; Assie, M. (Orsay, IPN) ; Balibrea, J. (Madrid, CIEMAT) ; Banerjee, K. (Calcutta, VECC) ; Bhattacharya, C. (Calcutta, VECC) ; Borge, M.J.G. (CERN ; Madrid, Inst. Estructura Materia) ; Cano-Ott, D. (Madrid, CIEMAT) ; Fernandez-Domınguez, B. (Santiago de Compostela U.) et al.
The kinematics of two-neutron emission following the $\beta$-decay of $^{11}$Li was investigated for the first time by detecting the two neutrons in coincidence and by measuring their angle and energy. An array of liquid-scintillator neutron detectors was used to reject cosmic-ray and $\gamma$-ray backgrounds by pulse-shape discrimination. [...]

The nuclear structure of the 31Mg nucleus has been studied with the singleneutron knockout reaction. We report on the preliminary results of an experiment performed with the EXOGAM array coupled, for the first time, to the SPEG spectrometer at GANIL.We present a provisional result for the inclusive single-neutron knockout cross section of σinc= 90(5) mb.

A new and independent determination of the Gamow-Teller branching ratio in the beta-decay of 21Na is reported. The value obtained of 5.13 +- 0.43 % is in agreement with the currently adopted value and the most recent measurement. [...]
