Observation of the First Excited State in 23O
N. Frank, A. Schiller, T. Baumann +12
The first excited state in neutron-rich 23O was observed in a (2p1n) knock-out reaction from 26Ne on a beryllium target at a beam energy of 86 MeV/A. The state is unbound with resp…
Population of neutron unbound states via two-proton knockout reactions
N. Frank, T. Baumann, D. Bazin +12
The two-proton knockout reaction 9Be(26Ne,O2p) was used to explore excited unbound states of 23O and 24O. In 23O a state at an excitation energy of 2.79(13) MeV was observed. There…
Exploring Neutron-Rich Oxygen Isotopes with MoNA
N. Frank, T. Baumann, D. Bazin +12
The Modular Neutron Array (MoNA) was used in conjunction with a large-gap dipole magnet (Sweeper) to measure neutron-unbound states in oxygen isotopes close to the neutron dripline…
Selective population and neutron decay of the first excited state of semi-magic O-23
A. Schiller, N. Frank, T. Baumann +14
We have observed an excited state in the neutron-rich semi-magic nucleus O-23 for the first time. No such states have been found in previous searches using gamma-ray spectroscopy.…
