Abstrakt

The integral cross section of the 12C(n,p)12B

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 β decay of 12B

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.
