“…Based on the γ rays observed in our measurement, and the assignments found in evaluated data compilations of levels properties for 89 Zr [28], 90 Zr [29], 91 Zr [30], 92 Zr [31], 93 Zr [32] and 94 Zr [33] level schemes have been constructed and updated. In some cases the additional informations were obtained from more recent measurements.…”

Nuclei produced via multineutron transfer channels have been studied in 90Zr + 208Pb close to the Coulomb barrier energy in a fragment-γ coincident measurement employing the PRISMA magnetic spectrometer coupled to the CLARA γ-array. The selective properties of the reaction mechanism have been discussed in terms of states and their strength excited in the neutron transfer channels leading to 89-94Zr isotopes. A strong population of yrast states, with energies up to ~7.5 MeV has been observed. © 2015 Elsevier B.V

“…The decay data such as the half-life (T 1/2 = ln2/k) and c-ray emission probability (I c in Eq. (1) as well as the c-ray energy (E c ) used in the determination of the c-ray detection efficiency were taken from the ENSDF evaluation [33][34][35][36][37][38] obtained from the NuDat 2.6 database [39] and are summarized in Table 1. The Q-values and threshold energies calculated on the basis of the atomic mass evaluation by Wang et al [40] combined with the Q-tool system [41] are also presented in Table 1.…”

Y(a,x) reactions MC-50 cyclotron Stacked-foil activation technique Excitation functionOff line c-ray spectrometry a b s t r a c tThe excitation functions of 89g,m,90,91m,92m Nb, 88,89 Zr, and 87g,m,88,90m,91m Y from alpha-induced reactions on 89 Y were measured from their respective threshold to 45 MeV by using a stacked-foil activation technique at the MC-50 cyclotron of the Korean Institute of Radiological and Medical Sciences. The results were compared with the earlier reported data as well as with the theoretical values obtained from the TENDL-2013 library based on the TALYS1.6 code. Our measurements in the energy region from the threshold energy to 45 MeV are in general good agreement with the other experimental data and calculated results. The integral yields for thick target of the produced radionuclides were also deduced from their measured cross sections and the stopping power of 89 Y. The measured excitation functions find importance in various practical applications including nuclear medicine and improvement of nuclear model calculations.

Background: While the N = 50 shell-gap evolution towards 78 Ni is presently in the focus of nuclear structure research, experimental information on the neutron effective single-particle energy sequence above the 78 Ni core remain scarce. Direct nucleon-exchange reactions are indeed difficult with presently available post-accelerated radioactive-ion beams (especially for high orbital-momentum orbitals) in this exotic region. Purpose: In this study we probe the evolution of the ν1g 7/2 effective single-particle energy which is a key to understanding the possible evolution of the spin-orbit splitting due to the proton-neutron interaction in the 78 Ni region. To achieve this goal, a method based on lifetime measurements is used for the first time. The obtained lifetimes of the 7/2 + 1 states in 87 Kr and 85 Se are used to investigate the ν1g 7/2 evolution. Method: Yrast and near-yrast states in the light N = 51 isotones 85 Se and 87 Kr were populated via multinucleon transfer reactions, using a 82 Se beam and a 238 U target at the LNL tandem-ALPI facility. The prompt γ rays were detected by the AGATA Demonstrator and particle identification was performed using the PRISMA spectrometer. Lifetime measurements were performed by using the Cologne plunger device for deep inelastic reactions and the Recoil Distance Doppler Shift technique. Results: We obtain τ (7/2 + 1 ) = 0.4 +1.6 −0.4 ps for 87 Kr. In the case of 85 Se an upper limit of 3(2) ps is obtained for the τ 7/2 + 1 value. Conclusion: For 87 Kr, the measured (7/2 + 1 ) lifetime is consistent with a core-coupled 2 + ⊗ ν2d 5/2 configuration for this state. This result is consistent with that obtained by direct reaction, which validates our method. For 85 Se, the measured 7/2 + 1 lifetime limit indicates a very small contribution of the ν1g 7/2 configuration to the wave function of this state.
