Description
Measurements were carried out of the angular distributions of the differential cross sections of the reaction products 7Li+10B ELAB = 58 MeV. One of the objectives of the measurements was to compare the root-mean-square radii of the ground and excited states of nuclei obtained in the reaction. In the experiment, the angular distributions of 7Lig.s, 6Lig.s, 6Li(3.56 MeV), as well as 11B(8.56 MeV) were of interest. The 6Li nucleus is in the Jπ=0+; T=1; E=3.56 MeV is the isobaric analogue state of 6Heg.s. The 11B nucleus is in the Jπ=3/2- state; E=8.56 MeV, according to [1], is a cluster state, similar to the previously discovered Hoyle state 12C*, Jπ =0+; T=0; E=7.65 MeV, predicted in [2] and first discovered in [3] by measuring the angular distributions of differential cross sections. The measurements were carried out on the 7Li beam (ELAB = 58 MeV) of the U-400 accelerator of the FLNR JINR using 8 dE-E semiconductor telescopes. A typical two-dimensional dE-E spectrum is shown in Fig. 1.
