Coulomb and Nuclear Breakup of 8 B Typeset Using Revt E X 1
نویسنده
چکیده
The cross sections for the (8 B, 7 Be-p) breakup reaction on 58 Ni and 208 Pb targets at the beam energies of 25.8 MeV and 415 MeV have been calculated within a one-step prior-form distorted-wave Born approximation. The relative contributions of Coulomb and nuclear breakup of dipole and quadrupole mul-tipolarities as well as their interference have been determined. The nuclear breakup contributions are found to be substantial in the angular distributions of the 7 Be fragment for angles in the range of 30 •-80 • at 25.8 MeV beam energy. The Coulomb-nuclear interference terms make the dipole cross section larger than that of quadrupole even at this low beam energy. However, at the incident energy of 415 MeV, these effects are almost negligible in the angular distributions of the (7 Be-p) coincidence cross sections at angles below 4 • .

The breakup of 8 B on 58 Ni below the Coulomb barrier was measured recently with the aim of determining the Coulomb breakup components. We reexamine this reaction, and perform one step quantum-mechanical calculations that include E1, E2 and nuclear contributions. We show that the nuclear contribution is by no means negligible at the intermediate angular range where data was taken. Our results i...

The three-nucleon photodisintegration of 3 He has been calculated in the whole phase space using consistent Faddeev equations for the three-nucleon bound and scattering states. Modern nucleon-nucleon and 3N forces have been applied as well as different approaches to nuclear currents. Phase space regions are localized where 3N force effects are especially large. In addition semi-exclusive cross ...

The multiplet structure induced by the Coulomb interactions in C 60 (n = 1 − 12) is analyzed. The partially ocuppied LUMO gives rise to a set of levels which fill a relatively wide band ( ≈ 2 − 3 eV ). A large (∼ 1 eV) intramolecular effective repulsion is found. The anions are also shown to be highly polarizable. The optical absorption and photoemission spectra are calculated. The probability ...

The Coulomb dissociation method to obtain the astrophysical S-factor, S 17 (0), for the 7 Be(p, γ) 8 B reaction at solar energies is investigated by analysing the recently measured data on the breakup reaction 208 Pb(8 B, 7 Be p) 208 Pb at 46.5 MeV/A beam energy. Breakup cross sections corresponding to E1, E2 and M 1 transitions are calculated with a theory of Coulomb excitation that includes t...
