G-frames and Hilbert-Schmidt operators
In this paper we introduce and study Besselian $g$-frames. We show that the kernel of associated synthesis operator for a Besselian $g$-frame is finite dimensional. We also introduce $alpha$-dual of a $g$-frame and we get some results when we use the Hilbert-Schmidt norm for the members of a $g$-frame in a finite dimensional Hilbert space.
متن کاملGorkov self-consistent Green’s function calculations of semi-magic nuclei
The first nuclear structure application of the newly developed Gorkov selfconsistent Green’s function method is presented. The approach aims to describe many-nucleon systems from an ab-initio standpoint featuring an explicit treatment of pairing correlations. In the present work calculations of binding energies of calcium isotopes are reported and compared with experimental data and other theor...
متن کاملHigh-spin studies and nuclear structure in three semi-magic regions of the chart: High-seniority states in Sn isotopes
Two fusion-fission experiments have been performed and studied with the Euroball Ge array: 12C+ 238U at 90MeV bombarding energy, and 18O+ 208Pb at 85MeV. Among the lot of new information extracted during the last decade, the latest results discussed here are the discovery of the high-spin states of 119–126Sn. The maximum value of angular momentum available in the νh11/2 shell, i.e. for mid-occu...
متن کاملIsomers and Seniority in the Trans-Pb Nuclei
Low-energy excited states of 210Ra and 208Ra were investigated at the Wright Nuclear Structure Laboratory of Yale University. Fusion evaporation recoils were selected using the gas-filled spectrometer, SASSYER. Delayed γ -rays, following isomeric decays, were detected at the focal plane of SASSYER with a small array of HPGe detectors. Transitions following the proposed J = 8+ isomers were obser...
متن کاملGeneralized seniority from random Hamiltonians
We investigate the generic pairing properties of shell-model many-body Hamiltonians drawn from ensembles of random two-body matrix elements. Many features of pairing that are commonly attributed to the interaction are in fact seen in a large part of the ensemble space. Not only do the spectra show evidence of pairing with favored J = 0 ground states and an energy gap, but the relationship betwe...
