The First Excited State of 9B

Halflife of the first excited state (0+) of 68Ni

2014 The confirmation of the 0+ spin assignment and the halflife value of the first excited state of 68Ni has been derived from the time spectra obtained in the coincidence measurement of the 160 from the 70Zn(14C, 16O)68Ni * reaction with the electrons associated to the decay of this level.

Nature of the First Excited State of 4 He

We study the first excited state of He in a microscopic {H + p,He + n} cluster model, including H and He distortions. The phenomenological S0 H+p scattering phase shift is well reproduced. We localize a complex pole of the S-matrix between the H+ p and He+n thresholds. The corresponding resonance parameters are Er = 93 keV position relative to H+p, and Γ = 390 keV width. A pole search is also p...

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...

Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives

The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...
