The radiation emitted by $180\ensuremath{-}\mathrm{GeV}∕c$ volume-reflected electrons and positrons impinging on a bent crystal has been measured the H8RD22 Collaboration H8 beamline at CERN SPS. A dedicated spectrometer developed to measure high-energy photon spectra (up $\ensuremath{\sim}100\phantom{\rule{0.3em}{0ex}}\mathrm{GeV}$) under volume reflection: charged particle beams have separated bending magnet leptons were detected tagged microstrip silicon detectors Pb-scintillator sampling...
Deflection due to planar channeling and volume reflection in short bent silicon crystals was observed for the first time 150 GeV/c negative particles, π− mesons, at one of secondary beams CERN SPS. The deflection efficiency about 30% higher than 80% reflection. Volume occurs, spite attractive character forces acting between particles crystal planes, a wide angular range orientations determined by bend angle.
Bent silicon crystals mounted on high-accuracy angular actuators were installed in the CERN Super Proton Synchrotron (SPS) and extensively tested to assess feasibility of crystal-assisted collimation circular hadron colliders. The adopted layout was exploited regularly upgraded for about a decade by UA9 Collaboration. investigations provided compelling evidence strong reduction beam losses induced nuclear inelastic interactions aligned comparison with amorphous orientation. A conceptually...
Executive functions are supported by a goal-directed manipulation of representations. On the other hand, metacognition reflects evaluation and control own Several studies focus on specific aspects these processes, but none formalize neuro-representational computations underlying their interaction during behaviour. Therefore, clear comprehensive frameworks model-based neuropsychological investigations prevented.Here we address issues exploiting `neuropsychological digital-twin method', thus...
Isomeric yield ratios for the odd-$A$ isotopes of $^{119--127}\mathrm{Cd}$ and $^{119--127}\mathrm{In}$ from 25-MeV proton-induced fission on natural uranium have been measured at JYFLTRAP double Penning trap, by employing phase-imaging ion-cyclotron-resonance technique. With significantly improved mass resolution this novel method isomeric states separated 140 keV ground state, with half-lives order 500 ms, could be resolved. This opens door obtaining new information low-lying isomers,...
We report the first experimental determination of independent isomeric yield ratios using direct ion counting with a Penning trap, which offered such high resolution in mass that states could be separated. The measurements were performed at Ion Guide Isotope Separator On-Line (IGISOL) facility University Jyv\"askyl\"a. isomer production $^{81}\mathrm{Ge}$, $^{96,97}\mathrm{Y}$, $^{128,130}\mathrm{Sn}$, and $^{129}\mathrm{Sb}$ 25-MeV proton-induced fission $^{\mathrm{nat}}\mathrm{U}$...
Multiple volume reflection by different planes passing through the ⟨111⟩ axis in a bent silicon crystal was observed for first time 150 GeV/c negative particles, π− mesons, at one of secondary beams CERN SPS. The beam mesons deflected opposite to bend an angle about 48 μrad, which is 4.6 times larger than single (110) planes. one-side deflection efficiency 65%. transforms when orientation relative direction increased.
Experimental and computational studies propose that inner speech boosts categorisation skills executive functions, making human behaviour more focused flexible. In addition, many clinical highlight a relationship between poor inner-speech an impairment in autism spectrum condition (ASC), but contrasting findings are reported. Here we investigate the latter issue through previously implemented validated model of Wisconsin Cards Sorting Tests. particular, was applied to detect individual...

The first systematic measurement of neutron-induced fission yields has been performed at the upgraded IGISOL-4 facility University Jyväskylä, Finland. products from high-energy nat U were stopped in a gas cell filled with helium buffer gas, and online separated dipole magnet. isobars, masses range A = 128-133 , transported to tape-implantation station identified using $ \gamma$ -spectroscopy.

The fission product yields are an important characteristic of the process. In fundamental physics, knowledge yield distributions is needed to better understand For nuclear energy applications good neutroninduced fission-product for safe and efficient operation power plants. With Ion Guide Isotope Separator On-Line (IGISOL) technique, products reactions stopped in a buffer gas then extracted separated by mass.
