The short-lived 8Be level at Ex=11.4 MeV

Measurements of the differential cross section for the 7Li(d, alpha alpha n) reaction have been performed at incident deuteron energy Ed=19.7 MeV. An appropriate kinematical configuration was chosen to observe the population of the second excited 8Be level. The values of (11.3+or-0.2) MeV for the excitation energy and of (3.7+or-0.2) MeV for the width of the above level were found. The influence of the transformation Jacobian on the determination of the two spectroscopic parameters is discussed.

Reaction mechanism and nuclear-rainbow effect in the3He+12C interaction atE(3He)=98 MeV

SummaryNuclear-rainbow effects in elastic and inelastic scattering and transfer reactions by the3He+12C interaction atE(3He)=98 MeV are observed, analyzing the angular distributions of the3He,2H and4He particles. The data are analyzed by a near/far-side formalism using Fullers model. We also observe the different characteristics of the rainbow effects and of the shape of the angular distributions for various reaction mechanisms.

Spectroscopic parameters of theJπ=1+,T=0 excited6Li level

An analysis of thed-α coincidence spectra of the7Li(3He, αd)4He reaction at incident energy of 5.0 MeV and at various detector angles has been carried out. The values of the spectroscopic parameters of theJπ=1+,T=06Li state at excitation energy of 5.65 MeV have been deduced. The results, considering the experimental errors, do not appear to be dependent on the geometry and are in line with the ones adopted in literature.
