The 5.65 MeV ⁶Li Level Width by the ⁷Li(³He, αd)α Reaction at E(³He)=11.5 MeV

抄録

The αd bidimensional spectra for the ⁷Li(³He, αd)α reaction at E(³He)=11.5 have been measured. The width of the (J^π=1⁺, T=0) level of the ⁶Li nucleus at E_x=5.65 MeV excitation energy have been deduced. The Γ value of (1.6±0.3) MeV found is in line with the values deduced by the same reaction at incident energies of E(³He)=2.5 and 5.0 MeV. This shows that, in the range between 2.5 and 11.5 MeV, the apparent Γ width value does not seem to depend on the ³He bombarding energy.
