In neutron-rich nucleosynthesis scenarios the mass gaps A = 5, 8 are assumed to be bridged by threebody electromagnetic recombination reaction α(αn, γ)9Be. We suggest an alternative path: the nuclear four-body neutron-recoil recombination reaction α(αnn, n)9Be. A qualitative estimate of the reaction rate for the alternative reaction shows that for higher neutron densities the rate is comparable with the electromagnetic rate.
