Add to ORKGWe report on the positron to electron ratio in the cosmic radiation over more than one decade in energy from 0.85 to 14 GeV, using the NMSU-WiZard/CAPRICE balloon borne magnet spectrometer. The spectrometer uses a solid radiator RICH detector and a silicon-tungsten calorimeter for particle identification. The proton rejection factor of the two instruments combined is better than 2 × 10-6 between 0.6 and 3 GV/c dropping to 6 × 10-5 at 5 GV/c and 10-4 at 10 GV/c. The data was collected during 23 hours at a mean residual atmosphere of 4.0 g/cm2. Prom a total of 2756 well identified e- and 498 e+ we are able to construct the positron fraction R = e+ /(e+ + e-) as a function of energy with small errors from 0.85 GeV to 14 GeV for the first tim...
