Abstract : Experimental values are presented of the annihilation rates in gases of slow positrons which have failed to form positronium. The observed values for argon, methane, ethane, propane, n-butane, isobutane, and carbon tetrachloride are found to exceed the values derived from the Dirac theory by factors ranging from 3 to 700.
