Abstract

Nuclear structure data pertaining to all nuclides with mass number A=92 have been compiled and evaluated, and incorporated into the ENSDF data file. All literature available by 7 November 2000 has been considered. This evaluation supersedes the previous publication for this mass chain (Coral M. Baglin, Nuclear Data Sheets 66, 347 (1992) (May 1992 cutoff data)), and all subsequent unpublished reevaluations incorporated into the ENSDF file prior to the present work.

Seniority in quantum many-body systems. I. Identical particles in a single shell
2014, Annals of Physics
A discussion of the seniority quantum number in many-body systems is presented. The analysis is carried out for bosons and fermions simultaneously but is restricted to identical particles occupying a single shell. The emphasis of the paper is on the possibility of partial conservation of seniority which turns out to be a peculiar property of spin-9/2 fermions but prevalent in systems of interacting bosons of any spin. Partial conservation of seniority is at the basis of the existence of seniority isomers, frequently observed in semi-magic nuclei, and also gives rise to peculiar selection rules in one-nucleon transfer reactions.
Calculation and analysis of n+<sup>90,91,92,94,96,nat</sup>Zr reactions in the E<inf>n</inf> ≤ 250 MeV energy range
2010, Annals of Nuclear Energy
Citation Excerpt :
The code DWUCK4 (Kunz, 1994) of the distorted wave Born approximation theory is used to precalculate the direct inelastic cross sections and angular distributions of discrete levels. The discrete levels were taken from nuclear data sheets (Browne, 1997; Baglin, 1999, 2000; Abriola and Sonzogni, 2006, 2008), and levels above the highest excited state are assumed to be overlapping and level density formula of the Back-Shifted Fermi gas (Dilg et al., 1973) and the Ignatyuk models (Ignatyuk et al., 1975) are used. Since the angular momentum and parity conservation in nuclear reactions, and the spin and parity of the ground state of 90,92,94,96Zr are 0 and the positive parity, the direct inelastic scattering cross sections are mainly from the contribution of the excited states that the spin and parity are 2+ and 3−.
All of reaction cross sections, angular distributions, energy spectra, γ-ray production cross sections, and the double differential cross section for neutron, proton, deuteron, triton, helium and alpha emission are calculated and analyzed for n+^{90,91,92,94,96,nat}Zr at incident neutron energies from 0.1 to 250 MeV. The optical model, intranuclear cascade model, the unified Hauser–Feshbach theory and the exciton model which included the improved Iwamoto–Harada model are used. Theoretical calculated results are compared with existing experimental data and other evaluated data from ENDF/B-VI.8, ENDF/B-VII.0 and JENDL-3.3. The optical model potential parameters are obtained according to the experimental data of total, nonelastic cross sections and elastic scattering angular distributions.
Magnetic behavior of isolated Mo impurities in antiferromagnetic Cr metal
2008, Solid State Communications
We report experimental and theoretical studies on the magnetic moment and hyperfine field of isolated Mo impurities in an antiferromagnetic Cr host. The magnetic response of ^92,94Mo, measured by means of the time differential perturbed angular distribution (TDPAD) technique, show the saturation hyperfine field $B_{hf} (0)$ to be $- 4.7 T$ . In addition, we find evidence of short range antiferromagnetic spin correlation above $T_{N}$ , revealed from the observation of large $B_{hf}$ values at temperatures far above $T_{N}$ . Our ab initio calculations, based on the generalized gradient approximation (GGA) of density functional theory (DFT), yield an induced magnetic moment of $0.45 μ_{B}$ for the Mo impurity in Cr. The magnitude of the calculated hyperfine field $B_{hf}^{cal} = - 3.35 T$ closely agrees with the experimental value. The results presented in this work would be helpful for a common understanding of hyperfine fields of impurity atoms in ferro- and antiferromagnetic materials.
