Shape dynamics in neutron-rich Kr isotopes: Coulomb excitation of $^{92}Kr$, $^{94}Kr$ and $^{96}Kr$
/ Albers, M (Cologne U.) ; Nomura, K (Cologne U.) ; Warr, N (Cologne U.) ; Blazhev, A (Cologne U.) ; Jolie, J (Cologne U.) ; Mücher, D (Munich, Tech. U.) ; Bastin, B (KU Leuven, FET) ; Bauer, C (Darmstadt, Tech. U.) ; Bernards, C (Yale U.) ; Bettermann, L (Cologne U.) et al.
We report on the study of excited states in $^{92,94,96}Kr$ populated via projectile Coulomb excitation at safe energies. The radioactive ion beams at energies of 2.85 MeV/u were delivered by the REX-ISOLDE facility at CERN and impinged on self-supporting $^{194,196}Pt$ targets. [...]

Normal and intruder configurations in $^{34}$Si populated in the $\beta^-$ decay of $^{34}$Mg and $^{34}$Al
/ IDS Collaboration
The structure of $^{34}$Si was studied through $\gamma$ spectroscopy separately in the $\beta^-$ decays of $^{34}$Mg and $^{34}$Al at the ISOLDE facility of CERN. Different configurations in $^{34}$Si were populated independently from the two recently identified $\beta$-decaying states in $^{34}$Al having spin-parity assignments $J^\pi = 4^-$ dominated by the normal configuration $\pi (d_{5/2})^{-1} \otimes \nu (f_{7/2})$ and $J^\pi = 1^+$ by the intruder configuration $\pi (d_{5/2})^{-1} \otimes \nu (d_{3/2})^{-1}(f_{7/2})^{2}$.

Nuclear moments of the low-lying isomeric 1$^+$ state of $^{34}$Al: Investigation on the neutron 1$p$1$h$ excitation across $N=20$ in the island of inversion
/ Xu, Z Y (Leuven U.) ; Heylen, H (Leuven U. ; CERN ; Heidelberg, Max Planck Inst.) ; Asahi, K (Nishina Ctr., RIKEN ; Tokyo Inst. Tech.) ; Boulay, F (CEA DAM) ; Daugas, J M (CEA DAM) ; de Groote, R P (Leuven U.) ; Gins, W (Leuven U.) ; Kamalou, O (GANIL) ; Koszorús, Á (Leuven U.) ; Lykiardopoulou, M (Athens U.) et al.
The nuclear $g$ factor and quadrupole moment ($Q_s$) have been measured for the low-lying isomeric $1^+$ state of $^{34}$Al, using the $\beta$-detected nuclear magnetic resonance ($\beta$-NMR) and quadrupole resonance ($\beta$-NQR) methods. Spin-polarized $^{34}$Al isotopes were produced in a one-neutron pickup reaction induced by a $^{36}$S beam on a $^9$Be target at a kinetic energy of 77.5 MeV/nucleon, and were collected with the LISE fragment separator at GANIL.

Properties of low-lying intruder states in 34Aland 34Sipopulated in the beta-decay of 34Mg
/ Lică, R (CERN) ; Rotaru, F ; Negoită, F ; Grévy, S ; Mărginean, N ; Desagne, Ph ; Stora, T (CERN) ; Borcea, C ; Borcea, R ; Călinescu, S et al.
The results of the IS530 experiment at ISOLDE revealed new information concerning several nuclei close to the N ≈ 20 'Island of Inversion' - 34Mg, 34Al, 34Si. The half-life of 34Mgwas found to be three times larger than the adopted value (63(1) ms instead of 20(10) ms). [...]

Properties of intruder states in $^{34}$Al and $^{34}$Si
/ Rotaru, F (Bucharest, IFIN-HH) ; Lica, R (Bucharest, IFIN-HH) ; Negoita, F (Bucharest, IFIN-HH) ; Grévy, S (CENBG, Gradignan) ; Marginean, N (Bucharest, IFIN-HH) ; Dessagne, Ph (Strasbourg, IPHC) ; Stora, T (CERN) ; Borcea, C (Bucharest, IFIN-HH) ; Borcea, R (Bucharest, IFIN-HH) ; Calinescu, S (Bucharest, IFIN-HH) et al.
We report on two experimental results for nuclei located in the region of the N = 20 island of inversion. In the first experiment, performed at GANIL, we have discovered and studied the $0_{2}^{ + }$ state in $^{34}$Si and made the hypothesis that it was fed by the beta-decay of a predicted isomeric $1^{+}$ state in $^{34}$Al.

Is the $7/2_1^-$ Isomer State of $^{43}$S Spherical?

We report on the spectroscopic quadrupole moment measurement of the 7/2−1 isomeric state in S271643 [E∗=320.5(5) keV, T1/2=415(3) ns], using the time dependent perturbed angular distribution technique at the RIKEN RIBF facility. Our value, ∣Qs∣=23(3) efm2, is larger than that expected for a single-particle state. [...]
