Observation of the First Excited State in 23
The first excited state in neutron-rich 23 O was observed in a (2p1n) knockout reaction from 26 Ne on a beryllium target at a beam energy of 86 MeV/A. The state is unbound with respect to neutron emission and was reconstructed from the invariant mass from the 22 O fragment and the neutron. It is unbound by 45(2) keV corresponding to an excitation energy of 2.8(1) MeV. The non-observation of fur...
متن کاملThe first excited states of 9 Be and 9 B
It is found here that the 1/2 + first excited state of 9 Be is a virtual state with the energy of-23.5 KeV. The line shape for the excitation of the state is approximated with a simple analytic form based on the effective range expansion. The partner in 9 B of this state is found to be a resonance with a maximum in the peak at about 1.1 MeV, FWHM of 1.5 MeV, and complex energy of 0.6 − i0.75 Me...

متن کاملFirst Observation of Bottom Baryon Σb States at CDF
We present the latest results on the search for bottom baryon states Σb using ∼ 1 fb of CDF data. The study is performed with the world’s largest sample of fully reconstructed Λb decays collected by CDF II detector at √ s = 1.96TeV in the hadronic trigger path. We observe 4 new states consistent with Σ (∗)± b bottom baryons.
متن کاملExcited states of 19Mg
We have calculated energies of the first two excited states of 19Mg by using a model that was previously successful for the ground state. Computed excitation energies are 1.12 and 1.54 MeV for (3/2−) and (5/2−), respectively—somewhat in disagreement with values of 1.38 and 2.14 MeV from a recent experiment.
