Single-particle decomposition of nuclear surface diffuseness
نویسندگان
چکیده
Abstract Nuclear surface diffuseness reflects spectroscopic information near the Fermi level. I propose a way to decompose into single-particle (s.p.) contributions in quantitative manner. Systematic behavior of neutron-rich even–even O, Ca, Ni, Sn, and Pb isotopes is analyzed with phenomenological mean-field approach. The role s.p. wave functions level explored: nodeless orbits form sharp nuclear surface, while nodal contribute diffusing surface.

How Nuclear Diffuseness Affects RHIC Data
The fact that nuclei have diffuse surfaces (rather than being simple spheres) has dramatic consequences on the interpretation of the RHIC heavy-ion data. The effect is quite small (but not negligible) for central collisions, but gets increasingly important with decreasing centrality. One may actually divide the collision zone into a central part (“core”), with expected high energy densities, an...
متن کاملSurface Diffuseness Anomaly in Heavy-ion Fusion Potentials
Recent high precision experimental data for heavy-ion fusion cross sections at energies in the vicinity of the Coulomb barrier systematically show that a strikingly large surface diffuseness parameter for a Woods-Saxon potential is required in order to fit the data. We discuss possible origins for this anomaly, including the effects of dissipation and the sensitivity of fusion cross sections to...

An IUCF-LANL-Princeton collaboration has been formed to measure the weak mixing between single-particle states in 207~b.132 The experiment was originally motivated by recent measurements at the Los Alamos Neutron Scattering Center by the TRIPLE c~l labora t ion .~ '~ As discussed below, it is now understood that the experiment has the potential of measuring the isoscaler weak amplitude in n ~ c...
متن کاملSingle Particle Spectrum and Binding Energy of Nuclear Matter
In non-relativistic Brueckner calculations of nuclear matter, the self-consistent single particle potential is strongly momentum dependent. To simplify the calculations, a parabolic approximation is often used in the literature. The variation in the binding energy value introduced by the parabolic approximation is quantitatively analyzed in detail. It is found that the approximation can introdu...
متن کاملSingle Particle Tracking of Surface Receptor Movement during Cell Division
We have used fluorescent latex beads to label membrane receptors on cultured NRK cells. Movement of individual beads during cell division was recorded with digital imaging techniques. Surface-bound beads showed no organized movement during metaphase but started to migrate toward the equator ,,ol min after anaphase onset, when chromosomes moved out of the equatorial region to create the interzon...
