Excited states and reduced transition probabilities in Os 168
(American Physical Society, 2016)
The level scheme of the neutron-deficient nuclide 168Os has been extended and mean lifetimes of excited states
have been measured by the recoil distance Doppler-shift method using the JUROGAM γ -ray spectrometer in
conjunction ...
Excited states in 217Ra populated in the α decay of 221Th
(American Physical Society (APS), 2020)
Fine structure in the α decay of 22190Th, populating excited states in 21788Ra, was studied using αγ-coincidence spectroscopy. Two α-decay branches from 221Th have been newly observed, with Eα(keV)[bα(%)]=7951(8)[0.14(3)] ...
Excited states in 31S studied via beta decay of 31Cl
(Springer, 2006)
The beta decay of 31Cl has been studied with a silicon detector array and a HPGe detector at the IGISOL facility. Previously controversial proton peaks have been confirmed to belong to 31Cl and a new proton group with an ...
Excited states in 87Br populated in β decay of 87Se
(American Physical Society, 2019)
Excited levels in 87Br, populated in β decay of 87Se, have been studied by means of γ-ray spectroscopy using an array of broad energy Ge detectors. 87Se nuclei were produced by irradiating a natural Th target with 25-MeV ...
Excited states in the proton-unbound nuclide 158Ta
(American Physical Society, 2016)
Excited states in the neutron-deficient odd-odd proton-unbound nuclide 158Ta have been investigated in two
separate experiments. In the first experiment, 166Ir nuclei were produced in the reactions of 380 MeV 78Kr
ions ...
Exclusive heavy vector meson electroproduction to NLO in collinear factorisation
(Springer Science and Business Media LLC, 2021)
We compute the exclusive electroproduction, γ*p → Vp, of heavy quarkonia V to NLO in the collinear factorisation scheme, which has been formally proven for this process. The inclusion of an off-shell virtuality Q2 carried ...
Exclusive Heavy Vector Meson Photoproduction on Nuclei in NLO Perturbative QCD
(Jagiellonian University, 2023)
We make predictions for the cross section of coherent J/ψ photoproduction in Pb–Pb and O–O ultraperipheral collisions (UPCs) at the LHC as a function of the J/ψ rapidity y in the framework of collinear factorization and ...
Exclusive heavy vector meson production at next-to-leading order in the dipole picture
(Elsevier BV, 2021)
We calculate exclusive production of a longitudinally polarized heavy vector meson at next-to-leading order in the dipole picture. The large quark mass allows us to separately include both the first QCD correction proportional ...
Exclusive J/ψ and ϒ production in high-energy pp and p-Pb collisions
(American Physical Society (APS), 2022)
We present a formalism for determining the cross section for exclusive heavy vector meson production (J/ψ,Υ) as a function of rapidity, in both high-energy proton-proton and proton-heavy ion collisions, at next-to-leading ...
Exclusive J/ψ photoproduction in ultraperipheral Pb+Pb collisions at the CERN Large Hadron Collider calculated at next-to-leading order perturbative QCD
(American Physical Society (APS), 2022)
We present the first next-to-leading-order (NLO) perturbative QCD (pQCD) study of rapidity-differential cross sections of coherent exclusive photoproduction of J/ψ mesons in heavy-ion ultraperipheral collisions (UPCs) at ...
