Resonant breakup of ⁸Be in ¹¹²Sn (⁷Li, ⁸Be → 2α) reaction

NUCLEAR REACTIONS ¹¹²Sn(⁷Li, ⁷Li), (⁷Li, ⁸Be), E=30 MeV; measured reaction products p, d, t, α, ⁶He and ^6,7Li, Eα, Iα, αα-coin, differential σ(θ) from α+α breakup of ⁸Be in proton pickup channel, elastic scattering and transfer channels using double sided silicon strip detector array at the 14-UD Pelletron-Linac TIFR-BARC facility; deduced large angular separation of the α fragments. ⁸Be; deduced resonances, J, π, widths, σ for α+α sequential breakup of ⁷Li to ⁸Be and then to α+α through the 0+, 2+, and 4+ resonances in ⁸Be. ¹¹³Sb, ¹¹³Sn; deduced differential σ(θ) for g.s. and excited states through proton and neutron stripping channels. Comparison with CDDC plus CRC calculations using FRESCO code.
