First results on ProtoDUNE-SP liquid argon time projection chamber performance from a beam test at the CERN Neutrino Platform
(Institute of Physics, 2020)
The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber with an active volume of 7.2× 6.1× 7.0 m3. It is installed at the CERN Neutrino Platform in a specially-constructed beam that delivers charged ...
First Ruthenium Complex of Glyoxalbis(N-phenyl)osazone (LNHPhH2): Synthesis, X-ray Structure, Spectra, and Density Functional Theory Calculations of (LNHPhH2)Ru(PPh3)2Cl2
(ACS, 2007)
The first ruthenium complex containing the parent osazone ligand, glyoxalbis(N-phenyl)osazone (LNHPhH2), is reported. The complex (LNHPhH2)Ru(PPh3)2Cl2 (1) was characterized with mass, IR, 1H NMR, and UV−vis spectroscopy ...
First spatial separation of a heavy ion isomeric beam with a multiple-reflection time-of-flight mass spectrometer
(Elsevier BV * North-Holland, 2015)
211Po ions in the ground and isomeric states were produced via 238U projectile fragmentation at
1000 MeV/u. The 211Po ions were spatially separated in flight from the primary beam and other reaction
products by the ...
First study of the two-body scattering involving charm hadrons
(American Physical Society, 2022)
This article presents the first measurement of the interaction between charm hadrons and nucleons. The two-particle momentum correlations of pD− and ¯pD+ pairs are measured by the ALICE Collaboration in high-multiplicity ...
First Study on Nihonium (Nh, Element 113) Chemistry at TASCA
(Frontiers Media SA, 2021)
Nihonium (Nh, element 113) and flerovium (Fl, element 114) are the first superheavy elements in which the 7p shell is occupied. High volatility and inertness were predicted for Fl due to the strong relativistic stabilization ...
First trap-assisted decay spectroscopy of the 81Ge ground state
(Springer, 2022)
The β-delayed γ spectroscopy of 81As has been performed using a purified beam of 81Ge (9/2+) ground state at the Ion Guide Isotope Separator On-Line facility (IGISOL). The 81Ge+ ions were produced using proton-induced ...
First β-decay scheme of 107Nb : New insight into the low-energy levels of 107Mo
(American Physical Society, 2019)
Monoisotopic samples of 107Nb nuclei, produced in the proton-induced fission of 238U and separated using the IGISOL mass separator coupled to a Penning trap, were used to perform β- and γ-coincidence spectroscopy of 107Mo. ...
First β-decay spectroscopy of 135In and new β-decay branches of 134In
(American Physical Society (APS), 2021)
The β decay of the neutron-rich 134In and 135In was investigated experimentally in order to provide new
insights into the nuclear structure of the tin isotopes with magic proton number Z = 50 above the N = 82
shell. The ...
First-forbidden transitions in reactor antineutrino spectra
(American Physical Society, 2019)
We study the dominant forbidden transitions in the antineutrino spectra of the fission actinides from 4 MeV
onward using the nuclear shell model. Through explicit calculation of the shape factor, we show the expected
changes ...
First-forbidden transitions in the reactor anomaly
(American Physical Society, 2019)
We describe here microscopic calculations performed on the dominant forbidden transitions in reactor antineutrino spectra above 4 MeV using the nuclear shell model. By taking into account Coulomb corrections in the most ...
