The reaction cross section for 8 B and 7 Be and the breakup cross section for 8 B on silicon have been measured for incident energies between 10 and 40 MeV/nucleon with a stack of silicon detectors. Secondary 8 B and 7 Be beams were obtained by use of the LISE spectrometer at GANIL. The stack of silicon detectors had the multiple purpose of slowing down the incident secondary beams, identifying the reaction products, and measuring their energy. The separate contributions of diffraction dissociation and absorption to the breakup have been determined. The parallel momentum distribution of 7 Be resulting from the breakup of 8 B has also been determined. The data are compared to theoretical calculations. ͓S0556-2813͑96͒06009-8͔

206 Pb( 6 He,2n) 210 Po, as well as for the transfer reactions on a 197 Au target with the formation of the 196 Au and 198 Au isotopes, with a beam dose about a factor of 10 higher and, in addition, at energies considerably lower than the Coulomb barrier of the reactions.

Secondary beams of 4He and 6He were produced through the transfer reactions with the 18.5 MeV/u lib and 35.5 MeV/u 7Li primary beams. The fusion-fission cross sections have been measured for the 4.6He + 209Bi reactions at energies Ecm> l.5*Bfus . In the present experiment it was found that the fission excitation function for the neutron rich nuclei 6He is significantly higher than for the 4He nuclei.

We have measured the differential cross-sections for the elastic as well as inelastic scattering populating the 2.43[Formula: see text]MeV [Formula: see text] excited state in [Formula: see text] using [Formula: see text] beams at energies of 30, 40 and 47[Formula: see text]MeV on a [Formula: see text] target. The experimental results for the elastic scattering were analyzed within the framework of the optical model using the Woods–Saxon and double-folding potentials. The theoretical calculations for the concerned excited states were performed using the coupled-channel method. The optimal deformation parameters for the excited states of [Formula: see text] nucleus were extracted.

Results of the measurements of the excitation function in the deuteron-induced reaction 45 Sc(d, p) 46 Sc have been obtained at the energy of incident deuterons up to 11.7 MeV. In addition, data for the 45 Sc(d, t) 44 Sc reaction were obtained. The experiments were performed using the variable energy cyclotron U-120M (NPI, Řež) and the Electrostatic Generator EG-5 (FLNP, JINR). The cross sections of the induced activities were measured using the stacked-foil technique. The measured excitation functions were similar to those observed for the 45 Sc( 6 He, 5 He * ) 46 Sc reaction, studied at the accelerator complex for radioactive beams DRIBs (FLNR, JINR). The maximum probability of producing 46 Sc was also found close to the Coulomb barriers of these reactions. The compilation of available experimental data, obtained at deuteron and 6 He-energies near the Coulomb barrier, showed that the values of the cross sections at the maxima of the excitation functions obtained in (d, p) reactions and the reactions for one-neutron pickup from the 6 He projectiles have a different Z-dependence.
