Radiative neutron capture rate of ${}^{11}$B$(n,\gamma {)}^{12}$B reaction from the Coulomb dissociation of ${}^{12}$B

Abstract

We calculate the ${}^{11}$B$(n,\gamma {)}^{12}$B reaction rate, an important constituent in nucleosynthesis networks, 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 ${}^{11}$B$(n,\gamma {)}^{12}$B reaction with those reported earlier and with other charged particle reactions on ${}^{11}$B.
