In the energy range of 3x102 ­ 5x105 eV/amu data for total and state selective electron capture in collisions of protons on helium have been evaluated critically. From this investigation we have constructed a set of recommended data which are part of the atomic database at JET and which, therefore, are used for modelling of He beam stopping and related diagnostics. The assessment of the cross sections is motivated and the corresponding uncertainties are inferred.
