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

Abstract

The integral cross section of the ${}^{12}$C($n,p$)${}^{12}$B reaction has been determined for the first time in the neutron energy range from threshold to several GeV at the n_TOF facility at CERN. The measurement relies on the activation technique, with the $\beta$-decay of ${}^{12}$B measured over a period of four half-lives within the same neutron bunch in which the reaction occurs. The results indicate that model predictions, used in a variety of applications, are mostly inadequate. The value of the integral cross section reported here can be used as a benchmark for verifying or tuning model calculations.
