First observation of the fine structure of the Pygmy Dipole Resonance in a nucleus away from stability via the decay of Rb to Sr
P. Spagnoletti, M. Ramalho, S. Tahtela +52
A comprehensive -ray spectroscopy study of excited states in Sr populated via decay of Rb (, ~keV) was performed with the GRIFFIN spect…
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 of…
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…
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 and…
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…
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 2.4…
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 , $3…
study of states in : Implications for new physics searches with xenon detectors
B. M. Rebeiro, S. Triambak, P. E. Garrett +21
We used the Ba reaction to carry out an in-depth study of states in Cs, up to around 2.5~MeV. In this work, we place emphasis on hitherto unobserved states b…
