Stability of the heaviest elements: $K$ isomer in $^{250}\mathrm{No}$
/ Kallunkathariyil, J (IRFU, Saclay) ; Sulignano, B (IRFU, Saclay) ; Greenlees, P T (Jyvaskyla U.) ; Khuyagbaatar, J (Darmstadt, GSI) ; Theisen, Ch (IRFU, Saclay) ; Auranen, K (Jyvaskyla U.) ; Badran, H (Jyvaskyla U.) ; Bisso, F (Jyvaskyla U.) ; Brionnet, P (Strasbourg, IPHC) ; Briselet, R (IRFU, Saclay) et al.
Decay spectroscopy of $^{250}\mathrm{No}$ has been performed using digital electronics and pulse-shape analysis of the fast nuclear decays for the first time. Previous studies of $^{250}\mathrm{No}$ reported two distinct fission decay lifetimes, related to the direct fission of the ground state and to the decay of an isomeric state but without the possibility to determine if the isomeric state decayed directly via fission or via internal electromagnetic transitions to the ground state.

In-beam γ -ray and electron spectroscopy of $^{249,251}$Md
/ Briselet, R. (IRFU, Saclay) ; Theisen, Ch. (IRFU, Saclay) ; Sulignano, B. (IRFU, Saclay) ; Airiau, M. (IRFU, Saclay) ; Auranen, K. (Jyvaskyla U.) ; Cox, D.M.

The odd-$Z$ $^{251}$Md nucleus was studied using combined $\gamma$-ray and conversion-electron in-beam spectroscopy. Besides the previously observed rotational band based on the $[521]1/2^-$ configuration, another rotational structure has been identified using $\gamma$-$\gamma$ coincidences. [...]

Decay spectroscopy of the odd-proton nuclei $^{249}$Md and $^{251}$Md has been performed. High-$K$ isomeric states were identified for the first time in these two nuclei through the measurement of their electromagnetic decay. [...]

Resonances of 6He via the 8He(p,t)6He reaction
/ Lapoux, L (Saclay) ; Mougeot, X (Saclay) ; Keeley, N (Saclay ; Warsaw, Inst. Nucl. Studies) ; Drouart, A (Saclay) ; Alamanos, N (Saclay) ; Auger, F (Saclay) ; Avez, B (Saclay) ; Beaumel, D (Orsay, IPN) ; Blumenfeld, Y (Orsay, IPN) ; Dayras, R (Saclay) et al.
We investigated the low-lying spectroscopy of 6He via the 2-neutron transfer reaction induced by the 8He SPIRAL beam at 15.4 A.MeV on a proton-rich target. The light charged recoil particles produced by the direct reactions were measured using theMUST2 Si-strip telescope array. [...]
