Scattering of radioactive nuclei 6He and 3H by protons: Effects of neutron skin and halo in 6He, 8He, and 11Li

In an experimental study of 6He+p and 3H+p collisions at ∼70 A MeV, the elastic scattering angular distributions were measured and the known excited state 6He1.8∗ was observed. Comparative analysis of existing experimental data on proton elastic scattering by 4He, 6He, 6Li, 8He, 9Li, and 11Li was performed. Effects of valence neutrons were investigated using the eikonal approach. A difference between 11Li and 6,8He was found.

Density distribution of 8B studied via reaction cross sections

Abstract Reaction cross sections ( σ R ) for 8 B on Be, C and Al targets were measured at energies of 40 A and 60 A MeV. The density distribution of 8 B was studied through a χ 2 -fitting procedure on the σ R including the high-energy data using the optical limit of Glauber theory with assumptions on the enhancement of the σ R at low energies. The result shows a long tail in the density distribution. Large one-proton removal cross sections were also observed to support the existence of a long proton tail consistent with its binding energy.

Elastic and inelastic scattering of exotic nuclei

Abstract Experimental studies of 11 Li+p, 8 He+p, 6 He+p, 3 H+p, and 14 Be+p at E ∼ 65–75 A MeV are reported. The elastic scattering cross sections are measured. Effects of extended neutron distributions in 11 Li, 8 He, 6 He are investigated. Spectroscopy of 11 Li, 6 He, 14 Be is performed.

Projectile fragmentation reactions and production of nuclei near the neutron drip line

The production mechanism of projectile-like fragments at intermediate energies has been investigated to understand the mechanism itself and to make precise prediction of the secondary beam intensity for designing experiments. We focus the target dependence of momentum distributions and production cross sections of fragments. Measurement of longitudinal momentum distributions of projectile-like fragments ranging 3
