چکیده

We discuss calculations of three-body observables for the breakup of 8B on a 58Ni target at low energy using the coupled discretised continuum channels approach. Calculations of both the angular distribution of the 7Be fragments and their energy distributions are compared with those measured at several laboratory angles. In these observables there is interference between the breakup amplitudes from different spin-parity excitations of the projectile. The resulting angle and the energy distributions reveal the importance of the higher-order continuum state couplings for an understanding of the measurements.

Axial observables in d-->p--> breakup and the three-nucleon force.

We have measured three axial polarization observables in d-->p--> breakup with a polarized 270 MeV deuteron beam on a polarized proton target. Axial observables are zero by parity conservation in elastic scattering but can be easily observed in the breakup channel at the present energy. Based on a symmetry argument, the sensitivity of these observables to the three-nucleon force might be enhanc...

Two independent calculations of proton-deuteron elastic scattering observables including Coulomb repulsion between the two protons are compared in the proton lab energy region between 3 MeV and 65 MeV. The hadron dynamics is based on the purely nucleonic charge-dependent AV18 potential. Calculations are done both in coordinate space and momentum space. The coordinate-space calculations are base...

Few-body Systems Proton-deuteron Elastic Scattering for E > 0

We report on the rst reliable numerical results for proton-deuteron elastic scattering observables for energies above the deuteron breakup threshold , for the Paris potential. The calculations have been performed within the screening and renormalisation approach. The theoretical results are compared with experimental data of Sagara et al.

Significance Of Deuteron Breakup In A Halo Transfer Reaction

We discuss the quasi-adiabatic approximations to the three-body wavefunction in breakup processes, clarifying the assumptions underlying the model. This suggests alternative approximation schemes. Using different theoretical three-body models, calculated differential cross section angular distributions for the Be(p,d) reaction, for which new preliminary data have been reported at 35 MeV, are pr...
