Search for $^{22}$Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes
/ Fougères, Chloé (GANIL ; Argonne, PHY) ; de Oliveira Santos, François (GANIL) ; José, Jordi (Barcelona U. ; Barcelona, IEEC) ; Michelagnoli, Caterina (Laue-Langevin Inst.) ; Clément, Emmanuel (GANIL) ; Kim, Yung Hee (GANIL ; IBS, Daejeon, CENS) ; Lemasson, Antoine (GANIL) ; Guimarães, Valdir (Sao Paulo U.) ; Barrientos, Diego (CERN) ; Bemmerer, Daniel (HZDR, Dresden) et al.
Classical novae are thermonuclear explosions in stellar binary systems, and important sources of $^{26}$Al and $^{22}$Na. While gamma rays from the decay of the former radioisotope have been observed throughout the Galaxy, $^{22}$Na remains untraceable. [...]

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 $\pi (d_{5/2})^{-1} \otimes \nu (d_{3/2})^{-1}(f_{7/2})^{2}$. [...]

Timing performance of ZnO:Ga nanopowder composite scintillators
/ Turtos, Rosana M (Milan Bicocca U.) ; Gundacker, Stefan (CERN) ; Lucchini, Marco T (CERN) ; Procházková, Lenka (Prague, Tech. U.) ; Čuba, Václav (Prague, Tech. U.) ; Burešová, Hana ; Mrázek, Jan (ASCR, Prague) ; Nikl, Martin (Prague, Inst. Phys.) ; Lecoq, Paul (CERN) ; Auffray, Etiennette (CERN)
The implementation of nanocrystal-based composite scintilla-tors as a new generation of ultrafast particle detectors is ex-plored using ZnO:Ga nanopowder. Samples are characterized with a spectral-time resolved photon counting system and pulsed X-rays, followed by coincidence time resolution(CTR) measurements under 511 keV gamma excitation. [...]

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

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.
