Abstract

New data on the reactions pp → ppρ{variant}⁰, pn → pnρ{variant}⁰, pn → ppρ{variant}^-, pp → ppf⁰, and pn → pnf⁰ at 7, 11.6 and 19 GeV/c are used to study the reactions pN → NNρ{variant} and pN → NNf⁰ in terms of isospin amplitudes. In the ρ{variant} case there are three such amplitudes M^I₁I₂ where I₁ and I₂ are the isospins of the exchanges in a double peripheral diagram. The result is that the amplitude with I₁ = 1 and I₂ = 0 is dominating. The properties of this amplitude are such that it is likely to be dominated by the pair of exchanges ρ{variant} + η. In the f⁰ case there are only two amplitudes. It is found that the I₁ = I₂ = 0 amplitude is larger than the I₁ = I₂ = 1 amplitude and that it has an energy dependence such that it could be dominated by the pair of exchanges η + η.
