Abstract

Comparison of $A_{1}$ coherent production in Freon with production in $H_{2}$ implies a total $A_{1}$ -nucleon cross section $σ (A_{1} N) <~ ({0.5}_{- 0.2}^{+ 0.3}) σ (π N)$ with a further theoretical uncertainty of about 10%. The result appears to preclude the possibility, suggested by the Deck model, that the $ρ$ and $π$ in the $A_{1}$ are produced close together without appreciable interaction between them.
