Direct measurement of Enhanced octupole collectivity in 148Dy

P. Spagnoletti, V. Vedia, E. Yuksel +36

Excited states in $_{66}^{148}$ Dy were populated via $β^{+} / E C$ decay of $^{148 m}$ Ho using the GRIFFIN spectrometer at the TRIUMF ISAC-I facility. A combined measurement of the mean…

Direct measurement of $^{59}$ Cu( $p$ , $α$ ) $^{56}$ Ni precludes a strong NiCu cycle in Type-I X-ray bursts

N. Bhathi, J. S. Randhawa, R. Kanungo +36

Model-observation comparisons of type-I X-ray bursts (XRBs) can reveal the properties of accreting neutron star systems, including the neutron star compactness. XRBs are powered by…

Investigation of the Excited States of $^{114} Sn$ Using the GRIFFIN Spectrometer at TRIUMF

N. K. Syeda, P. Spagnoletti, C. Andreoiu +43

The semi-magic $^{110 - 122} Sn$ isotopes display signs of shape coexistence in their excited $0^{+}$ states, which, in contrast to the spherical $0^{+}$ ground states, are defor…

Coulomb Excitation of $^{80}$ Sr and the limits of the $N = Z = 40$ island of deformation

R. Russell, J. Heery, J. Henderson +33

The region of $N \approx Z \approx 40$ has long been associated with strongly deformed nuclear configurations. The presence of this strong deformation was recently confirmed through…

Identifying the spin trapped character of the $^{32}$ Si isomeric state

J. Williams, G. Hackman, K. Starosta +30

The properties of a nanosecond isomer in $^{32}$ Si, disputed in previous studies, depend on the evolution of proton and neutron shell gaps near the `island of inversion'. We have p…

Cross Sections of the $^{83}$ Rb(p, $γ)^{84}$ Sr and $^{84}$ Kr(p, $γ)^{85}$ Rb Reactions at Energies Characteristic of the Astrophysical $γ$ Process

M. Williams, B. Davids, G. Lotay +22

We have measured the cross section of the $^{83}$ Rb(p, $γ)^{84}$ Sr radiative capture reaction in inverse kinematics using a radioactive beam of $^{83}$ Rb at incident energies of 2.4…
