Investigation of octupole collectivity near the shape-transitional point

M. Spieker, L. A. Riley, P. D. Cottle +13

Enhanced octupole collectivity is expected in the neutron-deficient Ge, Se and Kr isotopes with neutron number and has indeed been observed for Ge. Shape c…

Accessing the Single-Particle Structure of the Pygmy Dipole Resonance in Pb

M. Spieker, A. Heusler, B. A. Brown +8

New experimental data on the neutron single-particle character of the Pygmy Dipole Resonance (PDR) in Pb are presented. They were obtained from and resonant proton…

Collective 2p-2h intruder states in Sn studied via -decay of In using GRIFFIN

K. Ortner, C. Andreoiu, M. Spieker +25

The low-lying structure of semi-magic Sn has been investigated through the -decay of In ( min) to study shape coexistence via the reduced transitio…

Experimental identification of the , state of Co and isospin symmetry in studied via one-nucleon knockout reactions

M. Spieker, D. Weisshaar, A. Gade +15

New experimental data obtained from -ray tagged one-neutron and one-proton knockout from Co is presented. A candidate for the sought-after state…

Two-neutron knockout as a probe of the composition of states in Mg, Al, and Si

B. Longfellow, A. Gade, J. A. Tostevin +12

Simpson and Tostevin proposed that the width and shape of exclusive parallel momentum distributions of the A-2 residue in direct two-nucleon knockout reactions carry a measurable s…

One-proton and one-neutron knockout reactions from Ni to the mirror pair Co and Ni

M. Spieker, A. Gade, D. Weisshaar +15

We present a high-resolution in-beam -ray spectroscopy study of excited states in the mirror nuclei Co and Ni following one-nucleon knockout from a projectile beam…
