Abstract

Absolute differential cross sections for elastic p⁷Be and p⁸B small-angle scattering were measured in inverse kinematics at an energy of 0.7 GeV/u at GSI Darmstadt. The hydrogen-filled ionization chamber IKAR was used as an active target to detect the recoil protons. The projectile tracking and isotope identification were performed with multi-wire proportional chambers and scintillation detectors. The measured cross sections were analysed using the Glauber multiple-scattering theory. The root-mean-square (rms) nuclear matter radii R_m=2.42(4) fm for ⁷Be and R_m=2.58(6) fm for ⁸B were obtained. The radial density distribution deduced for ⁸B exhibits a proton halo structure with the rms halo radius R_h=4.24(25) fm. A comparison of the deduced experimental radii is displayed with existing experimental and theoretical data.
