Direct measurement of Enhanced octupole collectivity in 148Dy

P. Spagnoletti, V. Vedia, E. Yuksel, Y. X. Yu et autres

Excited states in $^{148}_{~66}$Dy were populated via $β^+/EC$ decay of $^{148m}$Ho using the GRIFFIN spectrometer at the TRIUMF ISAC-I facility. A combined measurement of the mean lifetime of the $3_1^-$ level using the Generalized Centroid Difference (GCD) method and branching fraction of …

Independent Validation of Octupole Collectivity in radium-224 through lifetime measurements of low-lying negative-parity states

D. White, D. O'Donnell, A. A. Avaa, J. R. Murias et autres

The nucleus $^{224}$Ra is a key benchmark for octupole deformation and for theoretical descriptions of enhanced Schiff moments in reflection-asymmetric nuclei. While Coulomb-excitation measurements have established strong octupole collectivity in $^{224}$Ra, theoretical models predict that its intrinsic electric-dipole moment should be strongly …

N = 8 Shell Breaking in Be 12 from a Single-Particle Perspective

J. Chen, B.P. Kay, D.K. Sharp, L.P. Gaffney et autres

Experimental observations of the low-lying states in ^{12}Be and their accurate modeling play an essential role in understanding the disappearance of the N=8 magic number. Long-standing experimental ambiguities have been clarified using an one-neutron adding (d, p) reaction on ^{11}Be using the …

Coulomb excitation data for 208Pb measured with GRETINA and CHICO2

M. Matejska-Minda, Jack Henderson, J. Heery, M. Rocchini et autres

Data sets contain total, angle-integrated gamma-ray spectra, Doppler-corrected for 208Pb reaction kinematics. The first column contains gamma ray energy in keV, the second column contains the number of counts, and the third column contains uncertainties. Gamma-ray energy spectra were obtained from a …

Exploring the "southern" border of the Z > 82 octupole-deformation region

A. E. Barzakh, A. Andreyev, Z. Yue, L. Nies et autres

The changes in the mean-squared charge radii relative to 209Bi126 (δ〈r2〉N,126) and the magnetic dipole and electric quadrupole moments in 214−218Bi have been measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). Magnetic moments of odd-odd bismuth nuclei have been analyzed …

First Measurement of the Quadrupole Moment of the $2_{1}^{+}$ State in $^{110}Sn $

J. Cederkäll, C. Fahlander, P. Golubev, A. Knyazev et autres

The Sn isotopic chain, exhibiting double shell closures at 100 Sn and 132 Sn , is a key testing ground for theoretical models of the atomic nucleus. It was originally predicted that the transitional matrix elements between the first 2+ state and …
