II. EMPIRICAL FORMULA FOR ECITATION ENERGIES OF SINGLE AND DOUBLE ANALOG STATES IN THE F7/2 SHELL A. Symmetry Energy Formula
نویسنده
چکیده
We find that the excitation energies of single analog states for odd-even nuclei in the f7/2 shell with J=j=7/2 − and the J=0 double analog states in the even-even nuclei are well described by the formulas E∗ (j, T + 1) = b(T + X) and E∗ (0, T + 2) = 2b(T + X + 0.5),respectively, where T =| N − Z | /2 is usually the ground state isospin. It is remarkable to note that the parameter X accounts for the departures from the symmetry energy based predictions. Typeset using REVTEX

Roles of proton-neutron interactions in alpha-like four-nucleon correlations
An extended pairing plus QQ force model, which has been shown to successfully explain the nuclear binding energy and related quantities such as the symmetry energy, is applied to study the alpha-like four-nucleon correlations in 1f7/2 shell nuclei. The double difference of binding energies, which displays a characteristic behavior at N ≈ Z, is interpreted in terms of the alpha-like correlations...
متن کاملEffects of on-center impurity on energy levels of low-lying states in concentric double quantum rings
In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

متن کاملIdentification of observables in quantum toboggans
Schrödinger equations for “quantum toboggans” with real energies are given the generalized eigenvalue-problem form Hψ = EWψ where H 6= H and where W 6= W † 6= I. The consistent probabilistic interpretation of these models is provided. The new double-series formula for the necessary ad hoc metric Θ = Θ(H,W ) is derived which defines the acceptable inner products in the physical Hilbert space of ...
متن کاملDouble K -shell photoionization and hypersatellite x-ray transitions of 12 Z 23 atoms
Single-photon double K-shell ionization of low-Z neutral atoms in the range 12 Z 23 is investigated. The experimental method was based on measurements of the high-resolution Kα hypersatellite x-ray spectra following the radiative decay of the K-shell double-vacancy states excited by monochromatic synchrotron radiation. The photon energy dependence of the double K-shell ionization was measured o...
