Mechanism of the ¹¹B(α, t)¹²C reaction at an energy of 40 MeV, role of exchange processes and collective excitations

NUCLEAR REACTIONS ¹¹B(α, t)¹²C, E=40 MeV; measured Et, It(θ); deduced triton σ(E), σ(θ) to gs and to E^*=4.44, 7.65, 9.64, 14.08 MeV; calculated σ, σ(θ) using coupled reaction channels code FRESCO considering ⁸Be cluster exchange mechanism, optical potential in the entrance channel fitted to the published scattering data; deduced spectroscopic amplitudes to the selected discrete states in ¹²C; deduced little effect of couplings between excited states, arising from ¹²C nonsphericity in forward hemisphere, but strongly affect σ, dσ at large angles.
