Magnetoresistance data in p-SiGe samples is analysed using the Renormalisat
ion Group theories of Finkel'stein and Castellani et al. The interaction pa
rameter, gamma (2) is found to be of order one or larger than one, sufficie
nt to explain the metallic behaviour in terms of delocalising Coulomb inter
action corrections, Published by Elsevier Science B.V.
