Measurement of the 12C(n, p)12B cross section at n_TOF (CERN) by in-beam activation analysis

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.
