Systematic analysis of reaction cross sections of carbon isotopes
Abstract
We systematically analyze total reaction cross sections of carbon isotopes with N= 6-16 on a {sup 12}C target for wide range of incident energy. The intrinsic structure of the carbon isotope is described by a Slater determinant generated from a phenomenological mean-field potential, which reasonably well reproduces the ground-state properties for most of the even N isotopes. We need separate studies not only for odd nuclei but also for {sup 16}C and {sup 22}C to improve their wave functions. The density of the carbon isotope is constructed by eliminating the effect of the center-of-mass motion. For the calculations of the cross sections, we take two schemes, the Glauber approximation and the eikonal model using a global optical potential. Both the reaction models successfully reproduce low and high incident energy data on the cross sections of {sup 12}C, {sup 13}C, and {sup 16}C on {sup 12}C. The calculated reaction cross sections of {sup 15}C are found to be considerably smaller than the empirical values observed at low energy. We find a consistent parametrization of the nucleon-nucleon scattering amplitude, differently from previous ones. Finally, we predict the total reaction cross section of {sup 22}C on {sup 12}C.

Photoneutron cross sections for {sup 96}Zr: A systematic experimental study of photoneutron and radiative neutron capture cross sections for zirconium isotopes
Photoneutron cross sections were measured for {sup 96}Zr near neutron threshold with quasimonochromatic laser-Compton-scattering {gamma}-ray beams. A systematic analysis of photoneutron and radiative neutron capture data for zirconium isotopes within the statistical model calculation leads to a unified picture of low-energy {gamma}-ray strengths for zirconium isotopes that is described by the HFB + QRPA model of E1 strength supplemented with an extra {gamma} strength attributed to a giant M1 resonance. Results of the systematic analysis including radiative neutron capture cross sections for radioactive {sup 95}Zr and {sup 93}Zr nuclei are presented. -
Reaction cross sections of carbon isotopes incident on a proton
We systematically study total reaction cross sections of carbon isotopes with N=6-16 on a proton target for wide range of incident energies. An emphasis is put on the difference from the case of a carbon target. The calculations include the reaction cross sections of {sup 19,20,22}C at 40A MeV, the data of which have recently been measured at RIKEN. The Glauber theory is used to calculate the reaction cross sections. To describe the intrinsic structure of the carbon isotopes, we use a Slater determinant generated from a phenomenological mean-field potential, and construct the density distributions.
