Direct lifetime measurements via $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidences using a fast timing detector array consisting of ${\mathrm{LaBr}}_{3}(\mathrm{Ce})$ scintillators has been applied to determine the low-lying states in semimagic $(N=50)$ nucleus $^{94}\mathrm{Ru}$. The experiment was carried out as first series ``FAIR-0'' experiments with DESPEC experimental setup at Facility for Antiproton and Ion Research (FAIR). Excited $^{94}\mathrm{Ru}$ were...

Reduced transition probabilities have been extracted between excited, yrast states in the N=Z+2 nucleus 94Pd. The transitions of interest were observed following decays Iπ=14+, Ex=2129-keV isomeric state, which was populated projectile fragmentation a 124Xe primary beam at GSI Helmholtzzentrum für Schwerionenforschung accelerator facility as part FAIR Phase-0. Experimental information regarding reduced E2 strengths for 8+ and 6+ determined isomer-delayed Eγ1−Eγ2−△T2,1 coincidence method,...
The nature of $J^{\pi}=1^-$ levels $^{96}$Zr below the $\beta$-decay $Q_{\beta}$ value $^{96}$Y has been investigated in high-resolution $\gamma$-ray spectroscopy following $\beta$ decay as well a campaign inelastic photon scattering experiments. Branching ratios extracted from allow absolute $E1$ excitation strength to be determined for populated both reactions. combined data represents comprehensive approach wavefunction $1^-$ value, which are theoretical Quasiparticle Phonon Model. This...
Isomeric states of the neutron-rich isotope 189 73 Ta 116 were populated via fragmentation a primary beam 208 Pb ions at 1 GeV/u impinging on 9 Be target GSI, Darmstadt, Germany. The isotopes interest separated, identified and delivered to DESPEC setup. Two isomers deduced in their lifetimes measured based γ-ray time distributions.
Abstract High-spin states in the N = 128 nucleus 218 Th have been investigated following fusion–evaporation reactions, using recoil-decay tagging technique. Due to short-lived nature of ground state prompt γ rays correlated with α decay daughter 214 Ra. The level scheme representing excited has extended (16 + ) observation six previously unreported transitions. observations are compared results shell model calculations and within context systematics neighbouring nuclei.

Abstract Isotopes for nuclear medicine are scarce and expensive. Researchers worldwide exploring new production methods to avoid the dependence on reactors as sources satisfy future isotope demands. Photo-nuclear reactions have hitherto been used a tool studying structure. Laser wakefield accelerators (LWFAs) very compact capable of producing high energy electron beams. In this paper we investigate possibility using LWFAs produce 225 Ac via photo-spallation reactions.
Abstract Lifetimes of excited states in the K π = 0 − octupole band and γ -vibrational 228 Th have been measured using fast timing setup at University West Scotland (UWS).
