Abstract
| The proof is given for the existence of the reaction e/sup +/e/sup -/ to /sup +or-/h/sup -or+/ in the energy range 1400-2400 MeV, and its energy dependence is compared with that of e/sup +/e/sup -/ to e/sup +or-/E/sup -or+/, in the same experimental conditions of observation. The exponent of the s-dependence of the ratio alpha =(e/sup +/e/sup -/ to h/sup +or-/h/sup -or+/)/(e/sup +/e/sup -/ to e/sup +or-/e/sup -or+ /) is measured to be n=2.08+or-0.45, in the s-range (1.96-5.76)GeV/sup 2/, on the basis of 51 e/sup +/e/sup -/ to /sup +or-/h/sup -or+/ events and 8918 e/sup +/e/sup -/ to /sup +or-/e/sup -or+/ events observed.
