N2  - Measurements of electron drift velocities have been made in 0·4673% and 1·686% hydrogenkrypton mixtures at 293 K and values of E/ N from 0·08 to 2·5 Td with an estimated uncertainty of <±0·7%. The data have been used in conjunction with the H2 cross sections of England et aL (1988) to derive the momentum transfer cross section for krypton over the energy range 0·05 to 6·0 eV. The drift velocity data have also been used to test the Kr momentum transfer cross sections of Koizumi et aL (1986) and Hunter (personal communication 1988). The cross section of Koizumi et aL is clearly incompatible with the present measurements while the cross section of Hunter has been used to predict these measurements to within 1% to 3%.
