Description

New data on the reactions pp→pprho0, pn→pnrho0, pn→pprho-, pp→ppf0, and pn→pnf0 at 7, 11.6 and 19 GeV/c are used to study the reactions pN→NNrho and pN→NNf0 in terms of isospin amplitudes. In the rho case there are three such amplitudes Msup(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 rho+eta. 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 eta + eta. (Auth.)
