“…All the lines previously attributed to the β-n decay of 83 Ga by Winger et al [20] could be confirmed. We could also confirm some of the transitions in 82 Ge observed in additional spontaneous-fission and 82 Ga β-decay studies [25,27]. A set of previously unreported lines and their proposed assignment is listed in Table V.…”

Pygmy Gamow-Teller resonance in the N=50 region: New evidence from staggering of β -delayed neutron-emission probabilities

We report on the β-delayed neutron emission probability (P 1n) measurements of the 82,83,84 Ga (N = 51,52,53) precursors performed in one single experiment using the 3 He neutron-counter TETRA at the ALTO facility in Orsay. Altogether our results for the three A = 82,83, and 84 Ga precursors point towards a sizable P 1n staggering in the N = 50 region, similar to the one already observed just after the N = 28 shell closure in the K isotopes chain, hinting at a similar mechanism. We will discuss the possible microscopic origin of this behavior, i.e., the existence in the light N = 51 isotones of low-lying components of the so called pygmy Gamow-Teller resonance, already well established at Z = 36, and persisting toward 79 Ni.

“…When compared with the previously reported data, we have added several levels to this decay scheme at 3076, 3258, 4221, 5618, 6012, 6063, 6675 and 6819 keV, and tentatively at 1952, (Fig. 4) [26]. The inconsistency between the log(f t) values and the assigned spin for these levels maybe due to some amount of missing feeding to these levels.…”

Decays of neutron-rich nuclei 82,83 Zn and 82,83 Ga produced in proton-induced fission of 238 U were studied at the Holifield Radioactive Ion Beam Facility (HRIBF) using on-line mass separation and β-γ spectroscopy techniques. New γ-ray transitions were identified and level schemes, which include states at high excitation energies in the range between 3 to 7 MeV were constructed. These high energy levels were identified to be populated through allowed Gamow-Teller β-transitions, and their structure was interpreted with new shell model calculations. A β-delayed neutron branching ratio of 69±7% was deduced for 82 Zn and revised β-decay half-life values of 82 Zn (155(17)(20) ms) and 83 Zn (122(28) ms) were determined.

“…Interpreting these intensity modulations presents a complex problem that has been addressed recently for the case of single layer and some forms of bilayer graphene 3, 5 . Graphene presents a nearly ideal platform for exploring this phenomena for two reasons: (i) Graphene is a two dimensional material in which there is no dispersion of the quasiparticle bands due to a third (perpendicular) component of the crystal momentum.…”

“…The orientations of these dark corridors are rotated for photoemission from states near symmetry-related zone corner points when re-solved in the extended Brillouin zone. For AB-stacked bilayer graphene the emission patterns are more complex but they have been analyzed similarly to identify the sign of the dominant interlayer Hamiltonian matrix elements between neighboring sites in the adjacent layers 5 . Theory predicts that single layer graphene with a strong Rashba spin-orbit interactions should have a distinct photoemission signature in its spin-resolved ARPES reflecting the entanglement of its spin and orbital (pseudospin) degrees of freedom 6 .…”

Selection rules and interference effects in angle resolved photoemission spectra from twisted graphene bilayers are studied within a long wavelength theory for the electronic structure. Using a generic model for the interlayer coupling, we identify features in the calculated ARPES momentum distributions that are controlled by the singularities and topological character of its long wavelength spectrum. We distinguish spectral features that are controlled by single-layer singularities in the spectrum, their modification by gauge potentials in each layer generated by the interlayer coupling, and new energy-dependent interference effects that directly probe the interlayer coherence. The results demonstrate how the energy-and polarization-dependence of ARPES spectra can be used to characterize the interlayer coupling in twisted bilayer graphenes.
