“…The measurements of the momentum distribution of 7 Be fragments from the 8 B break-up reactions performed at GSI have shown a much narrower distribution than the one for stable nuclei [9]. Similar measurements have later been performed at different beam energies [10][11][12][13]. Moreover, the one-proton removal cross section is enhanced as compared to the case of a nucleus with a tightly bound proton [9,[12][13][14][15][16], what is also a signature for an extended valence-proton wave function.…”

Absolute differential cross sections for elastic p 7 Be and p 8 B 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 7 Be and R m = 2.58(6) fm for 8 B were obtained. The radial density distribution deduced for 8 B 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.

“…This formalism has been applied to proton breakup of 8 B against Pb and C targets at a beam energy of 936 A.MeV, experiment reported in [8]. The projectile 8 B is taken as a two-body object.…”

“…When comparing to experimental data, spectroscopic factors must be taken into account. Following [8], the spectroscopic factor for the excited state is S ex = 0.101 in this work, while for the ground state we have used S gs = 0.841. The latter has been obtained by adding together the spectroscopic factors for two states which differ in core intrinsic spin [8], since our formalism cannot distinguish between them.…”

These numbers provide an exclusive/inclusive ratio of R theo = 0.089 for the Pb target, in good agreement with the experimental result R exp = 0.085±0.021.…”

“…A number of experimental papers [3]- [13] have reported experiments on proton breakup from 8 B. 8 B is partner in (p,γ) radiative capture reactions of great astrophysical interest for the understanding of the neutrino flux from the sun (see for example the discussion and references of [5]). 17 F is another candidate for proton halo which is still under investigation both experimentally [14,15,16] as well as theoretically [17,18,19,20].…”

All orders proton breakup from exotic nuclei

We present a semiclassical method to treat the proton breakup from a weakly bound state in an exotic nucleus. The Coulomb interactions between the proton, core and target are treated to all orders and including the full multipole expansion of the Coulomb potential. The nuclear proton-target interaction is also treated to all orders. The core-target interaction is included as an absorption. The method is semi-analytical thus allowing for a detailed understanding of the short range and long range effects of the interactions in the reaction dynamics. It explains also the origin of possible asymmetries in the core parallel momentum distributions when the full multipole expansion of the Coulomb potential is used. Calculations are compared to results of other, fully numerical, methods and to experimental data in order to establish the accuracy and reliability of the method.Comment: 5 latex pages, 3 figures, 2 tables.
