First Evidence of Axial Shape Asymmetry and Configuration Coexistence in Zn: Suggestion for a Northern Extension of the Island of Inversion
M. Rocchini, P. E. Garrett, M. Zielinska +41
The excited states of Zn were investigated via -ray spectroscopy following Cu decay. By exploiting - angular correlation analysis, the …
Cross Sections of the Rb(p,Sr and Kr(p,Rb Reactions at Energies Characteristic of the Astrophysical Process
M. Williams, B. Davids, G. Lotay +22
We have measured the cross section of the Rb(p,Sr radiative capture reaction in inverse kinematics using a radioactive beam of Rb at incident energies of 2.…
The 76Cu conundrum remains unsolved
B. Olaizola, A. Illana, J. Benito +80
Near the doubly-magic nucleus \nuc{Ni}{78} (, ), there has been a decades-long debate on the existence of a long-lived isomer in \nuc{Cu}{76}. A recent mass measurement…
Coulomb Excitation of Sr and the limits of the island of deformation
R. Russell, J. Heery, J. Henderson +33
The region of has long been associated with strongly deformed nuclear configurations. The presence of this strong deformation was recently confirmed through…
Direct observation of proton emission in 11Be
Y. Ayyad, B. Olaizola, W. Mittig +30
The elusive $β^-\text{p}^+$ decay was observed in Be by directly measuring the emitted protons and their energy distribution for the first time with the prototype Active Ta…
Investigation of the Excited States of Using the GRIFFIN Spectrometer at TRIUMF
N. K. Syeda, P. Spagnoletti, C. Andreoiu +43
The semi-magic isotopes display signs of shape coexistence in their excited states, which, in contrast to the spherical ground states, are defor…
Absence of Low-Energy Shape Coexistence in Ge: The Nonobservation of a Proposed Excited 0 Level at 639 keV
F. H. Garcia, C. Andreoiu, G. C. Ball +28
The Ge structure was investigated in a high-statistics -decay experiment of Ga using the GRIFFIN spectrometer at TRIUMF-ISAC through , -, - and…
Intruder structures in Si and Al
J. Williams, G. Hackman, K. Starosta +31
We have studied Si and Al using C(Ne,2p) and C(Ne,p) fusion-evaporation reactions. In both cases, we observed significant population o…
First Direct Measurement of an Astrophysical p-Process Reaction Cross Section Using a Radioactive Ion Beam
G. Lotay, S. A. Gillespie, M. Williams +35
We have performed the first direct measurement of the 83Rb(p,g) radiative capture reaction cross section in inverse kinematics using a radioactive beam of 83Rb at incident energies…
High-Precision Branching Ratio Measurement and Spin Assignment Implications for Ga Superallowed Decay
A. D. MacLean, A. T. Laffoley, C. E. Svensson +48
A high-precision branching ratio measurement for the superallowed Fermi $β^{+}$ emitter Ga was performed with the Gamma-Ray Infrastructure for Fundamental Investigations of…
Cross-shell excited configurations in the structure of 34Si
R. S. Lubna, A. B. Garnsworthy, Vandana Tripathi +23
The cross-shell excited states of Si have been investigated via -decays of the ground state and the isomeric state of Al. Since the valence protons an…
Identifying the spin trapped character of the Si isomeric state
J. Williams, G. Hackman, K. Starosta +30
The properties of a nanosecond isomer in Si, disputed in previous studies, depend on the evolution of proton and neutron shell gaps near the `island of inversion'. We have p…
Decay Spectroscopy of Eu: Quasiparticle Configurations of Excited States and Structure of = Band-heads in Gd
D. Yates, R. Kruecken, I. Dillmann +45
\noindent \textbf{Background:} Detailed spectroscopy of neutron-rich, heavy, deformed nuclei is of broad interest for nuclear astrophysics and nuclear structure. Nuclei in the r-pr…
