Experiments to perform precision spectroscopy of fast neutron induced fission were carried out during the ν-Ball experimental campaign at ALTO facility IJC Laboratory Orsay. Low energy 232 Th(n,f), 238 U(n,f) and spontaneous 252 Cf studied using this hybrid highresolution spectrometer calorimeter. New observables such as γ-ray multiplicity distributions correlated with specific fragments are pr...

When mammalian social groups exceed their optimal size, they often tend to split. In view of the potential evolutionary benefits, it should be more advantageous for animals to stay with kin, rather than nonkin, during such fission events. In the present study, the spontaneous fission of two social groups, R and S, of rhesus macaques living on Cayo Santiago, Puerto Rico, provided the opportunity...

In the fission yeast Schizosaccharomyces pombe, S phase is limited to a single round per cell cycle through cyclin-dependent kinase phosphorylation of critical replication factors, including the Cdc18 replication initiator protein. Because defects in Cdc18 phosphorylation lead to a hyperstable and hyperactive form of Cdc18 that promotes high levels of overreplication in vivo, we wished to ident...

Decay properties of neutron-deficient isotopes of actinide elements provide valuable information on the nuclear mass surface close to the proton drip line, on nuclear structure of deformed heavy nuclei and on fission properties far from stability. However, detailed experimental data on decay properties of neutron-deficient nuclei in the region of Z>96 are still scarce due to low production rate...

We present first preliminary results of a novel method for measuring independent isotopic fission yields (IIFYs) spontaneous (SF) via direct mass measurements, at the FRS Ion Catcher (FRS-IC) GSI. Fission products were generated from 252 Cf source installed in cryogenic stopping cell, and identified counted with multiple-reflection time-of-flight spectrometer (MR-TOF-MS) FRS-IC, utilizing well-...

In this paper we propound a non­destructive and non­invasive technique for measuring the thickness of water penetration in a homogeneous slab. The proposed device consists of a 252 Cf spontaneous fission source and a set of 3 He detectors located on the same side of a concrete slab subject to water infiltration. The effectiveness of this technique has been investigated by Monte Carlo simulation...

Simulations of the neutron background for future large-scale particle dark matter detectors are presented. Neutrons were generated in rock and detector elements via spontaneous fission and (α,n) reactions, and by cosmic-ray muons. The simulation techniques and results are discussed in the context of the expected sensitivity of a generic liquid xenon dark matter detector. Methods of neutron back...
