The integral cross section of the 12C(n, p)12B reaction has been determined for the first time in the whole energy range from threshold to several hundred MeV at the n TOF facility at CERN. The measurements relies on the activation technique, with the beta-decay of 12B measured over a period of four half-lives within the same neutron bunch of the reaction. The production rate is extracted from a fit of the time distribution, taking into account the sample-related background and efficiency corrections with two different methods. The results of this work indicate that model predictions, used in a variety of applications, are mostly inadequate. The value of the integral cross section value reported here can be used as a benchmark for verifying or tuning model calculations.
