Discovery of an Iπ = 10 + Isomer in 150Yb: Nature of the Longest 10 + Isomeric Chain

W.Q. Zhang, Z. Liu, A. N. Andreyev, Y. X. Yu et autres

Delayed γ-ray spectroscopy was performed for evaporation residues produced in the 58Ni þ 96Ru reaction. A new isomer in 150 70Yb (Z ¼ 70, N ¼ 80) with a half-life of 0.62ð5Þ μs was identified at an excitation energy of 2872(2) keV. …

In-beam γ ray spectroscopy of 94Ag

X. Pereira-López, M. A. Bentley, R. Wadsworth, P. Ruotsalainen et autres

The fusion evaporation reaction 40Ca(58Ni,p3n)94 Ag has been used to study the odd-odd N=Z nucleus 94Ag at JYFL-ACCLAB using the MARA recoil separator and the JUROGAM 3 HPGe detector array. The recoil-β-tagging technique has allowed the observation of γ rays de-exciting states …

Emerging tension between isospin symmetry and nuclear deformation at A = 78

J. Henderson, D. G. Jenkins, J. Heery, C. Müller-Gatermann et autres

Since the nuclear interaction is, to first order, isospin independent, simple relationships can be derived for E2 strengths across isobaric analog states within an isobaric triplet. At the same time, there is a well-known relationship between the 2+ excitation energy and the …

Isospin symmetry breaking in the T = 1 , A = 70 triplet

G. Zimba, P. Ruotsalainen, G. De Gregorio, G. de Angelis et autres

Excited states in the $^{70}\mathrm{Kr}$ and $^{70}\mathrm{Br}$ nuclei were populated via the $^{40}\mathrm{Ca}(^{32}\mathrm{S},2n)^{70}\mathrm{Kr}$ and $^{40}\mathrm{Ca}(^{32}\mathrm{S},pn)^{70}\mathrm{Br}$ fusion-evaporation reactions at the Accelerator Laboratory of the University of Jyv\"askyl\"a. The ${2}^{+}\ensuremath{\longrightarrow}{0}^{+}$ and ${4}^{+}\ensuremath{\longrightarrow}{2}^{+}$ transitions in $^{70}\mathrm{Kr}$ have been found to be 881(1) keV and (tentatively) …

Superdeformation and prolate-oblate competition in Tl nuclei

D. Seweryniak, L. L. Riedinger, R. Wadsworth, Bradley H. Smith et autres

Spectroscopic studies of weakly populated proton i13/2 bands in superdeformed Tl nuclei (around mass 190) and in the normally deformed, very light 183Tl nucleus are discussed. Among the results presented, the first measurement of a superdeformed quadrupole moment in an odd-Z nucleus, …

A segmented total energy detector (sTED) for (n, γ) cross section measurements at n_TOF EAR2

V. Alcayne, D. Cano‐Ott, J. A. Benitez Garcia, E. González-Romero et autres

The neutron time-of-flight facility n_TOF is characterised by its high instantaneous neutron intensity, high-resolution and broad neutron energy spectra, specially conceived for neutron-induced reaction cross section measurements. Two Time-Of-Flight (TOF) experimental areas are available at the facility: experimental area 1 (EAR1), located …
