Charge sharing and alignment performance of bent ALPIDEs measured with low-energy protons
Berkin Ulukutlu, Christopher Ehrich, Laura Fabbietti +14
The upgrade of the ALICE experiments Inner Tracking System (ITS3) aims to replace its innermost detection layers with bent wafer-scale CMOS MAPS sensors. This study examines the pe…
The dipole strength distribution of He and decay characteristics
C. Lehr, T. Aumann, M. Duer +91
The weak binding and spatially extended neutron densities characteristic of drip-line nuclei give rise to a distinctive low-energy dipole response. The drip-line nucleus He is…
Direct observation of three-neutron emission from He and the search for the trineutron
S. W. Huang, C. Lenain, Z. H. Yang +107
Three-neutron emission from He has been directly measured for the first time, following neutron knockout from a He beam at 156 MeV/nucleon. A resonance-like structure at $2…
Establishing the Ca reaction at 392 MeV under quasi-free scattering conditions
Riku Matsumura, Junki Tanaka, Kazuki Yoshida +80
The reaction offers a direct means to probe preformed -cluster structures in nuclei under quasi-free scattering conditions. Previous studies around 100 MeV provided…
Recent Results on the Tetraneutron
Thomas Faestermann, Roman Gernhäuser
We describe the recent experiments which claimed an observation of a tetra-neutron signal. Production reactions like transfer, knockout, fragmentation or photodisintegration have b…
