ResumoFinal results are presented of the analysis of the elastic channel in an exposure of 40 000 pictures at each of the four incident K+ momenta 2.11, 2.31, 2.5 and 2.72 GeV/c taken in the 1.5 m British National Hydrogen Bubble Chamber at the 8 GeV/c proton synchrotron at the Rutherford High Energy Laboratory. Differential cross sections are presented and the results are compared with other published data. A Legendre polynomial analysis requires partial waves up to G wave at all momenta. For the backward peak, visible at each momentum, the slope and the intercept are calculated. A comparison of the forward peak is made with extrapolations from Regge models fitted at higher momenta.
