Identical Transitions in the Strongly Deformed 99 Sr and 100 Sr Typeset Using Revt E X 1
نویسندگان
چکیده
The decay of the very neutron-rich nucleus 100 Rb has been studied by γ-spectroscopy of on-line mass-separated samples. Schemes for β-decay to 100 Sr and βn-decay to 99 Sr are presented. New sets of transitions in 99 Sr and 100 Sr with identical energies are observed. All identical bands so far observed in neutron-rich Sr isotopes obey a simple energy rule valid for even-even, odd-even and odd-odd bands.

Identical transitions in the strongly deformed 99 Sr and 100
Neutron-rich isotopes with N>60 and A.100 are characterized by strong axial deformation. Strontium isotopes are the most deformed nuclei known so far in this region. Quadrupole deformations of b.0.4 have been deduced for Sr, Sr, and Sr from the lifetimes of the first excited states and from mean-square radii measured by collinear laser spectroscopy @1–5#. According to these results, ground-stat...
متن کاملDispersion of the Strongly Correlated Electron System near the Fermi Level Typeset Using Revt E X
The reason for the appearance of two distinct bands in the photoemission of the single CuO 2 plane Bi 2 Sr 2−x La x CuO 6+δ near the Fermi level is discussed on the basis of the self-consistent solution of the two-dimensional t-J model.
متن کاملProton Capture Cross Section of Sr Isotopes and Their Importance for Nucleosynthesis of Proton-rich Nuclides Typeset Using Revt E X 2
The (p,γ) cross sections of three stable Sr isotopes have been measured in the astrophysically relevant energy range. These reactions are important for the p-process in stellar nucleosynthesis and, in addition, the reaction cross sections in the mass region up to 100 are also of importance concerning the rp-process associated with explosive hydrogen and helium burning. It is speculated that thi...

We report on infrared reflectivity measurements of the ab-plane response of superconducting Bi2Sr2CuO6 single crystals. The frequency dependent conductivity has a maximum near 500 cm at room temperature, which shifts to lower frequency and merges with a Drude peak below 100 K. We attribute the unusual behavior of the mid-infrared conductivity to low frequency transitions between electronic band...

We adopt a t 1 − t 2 − t 3 − J − G model for explanation of x = 1/8 anomaly in La 2−x Sr x CuO 4 family compound. The calculated charge susceptibility shows a maximum near (π, π) at intermediate temperatures and near (π, π/2) as temperature approaches zero, in agreement with neutron scattering experiments. Coulomb repulsion G between the first neighbors turns out to be the source of Charge Dens...
