Radiative Neutron Capture Rate of $$^{11}$$B$$(n,\gamma )^{12}$$B Reaction from the Coulomb Dissociation of $$^{12}$$B

Abstract

We calculate the $$^{11}$$ 11 B$$(n,\gamma )^{12}$$ ( n , γ ) 12 B reaction rate which is an important constituent in nucleosynthesis networks and is contributed by resonant as well as non-resonant capture. For the resonant rate, we use the narrow resonance approximation whereas the non-resonant contribution is calculated with the Coulomb dissociation method for which we use finite-range distorted wave Born approximation theory. We then compare our calculated rate of $$^{11}$$ 11 B$$(n,\gamma )^{12}$$ ( n , γ ) 12 B reaction with those reported earlier and with other charged particle reactions on $$^{11}$$ 11 B.
