New lifetime measurements in the stable semimagic Sn isotopes using the Doppler-shift attenuation technique Open
Precise measurements of lifetimes in the picosecond range of excited states in the stable even-A Sn isotopes 112;114;116;122 Sn have been performed using the Doppler shift attenuation technique. For the rst excited 2 + states in 112 Sn, 11…

Evidence for reduced collectivity around the neutron mid-shell in the stable even-mass Sn isotopes from new lifetime measurements Open
Precise measurements of the lifetimes of the first excited 2+ states in the stable even-A Sn isotopes 112-124Sn have been performed using the Doppler shift attenuation technique. For the isotopes 112Sn, 114Sn and 116Sn the E2 transition st…

A Dual-Purpose Ion-Accelerator for Nuclear-Reaction-Based Explosives-and SNM-Detection in Massive Cargo Open
A dual-purpose ion-accelerator concept, capable of serving as radiation source in a versatile, nuclear-reaction-based cargo inspection system, is presented. The system will automatically and reliably detect small, operationally-relevant qu…

First measurement and shell model interpretation of the g factor of the 21+ state in self-conjugate radioactive 44Ti Open
The g factor of the 21+ state in radioactive 44Ti has been measured for the first time with the technique of α transfer to 40Ca beams in inverse kinematics in combination with transient magnetic fields, yielding the value, g(21+)=+0.52(15)…

Proton–neutron structure of the N=52 nucleus 92Zr Open
Following the successful identification of mixed-symmetric one- and two-phonon states in the N=52 nuclei 94Mo and 96Ru, we have performed a photon scattering experiment on the N=52 isotone 92Zr. Experimental data and shell model calculatio…
