The differential cross sections of 7Lig.s., 6Lig.s., 6Li3.56, 6Heg.s. reaction products emitted in the 7Li+10B collision are presented, measured for the first time in a single experiment under the same conditions. The measurements were performed using a 7Li beam at ELAB = 58 MeV from the U400 cyclotron at the FLNR, JINR, Dubna. The differential cross sections of 7Lig.s., 6Lig.s., 6Li3.56, and 6Heg.s. were measured in the angular range 11 < CM < 84◦. The angular distributions of the measured differential cross sections were analyzed using the finite-range-coupled reaction-channel approach. The theoretical analysis provides a fair description of the measured 6Li(0+ 1 ) + 11Bg.s. channel cross section, when the breakup process of the 6Li(0+ 1 ) excited state is explicitly included in the coupling scheme. It is demonstrated that the halo structure of 6He and its connection to the narrow resonance (the 2+ isobaric excited state of 6He formed in the one-proton stripping reaction) play a decisive role in describing the measured angular distribution for the population of the 6Heg.s.(0+) + 11Cg.s.(3/2−) channel.
