SENSITIVITY OF T20 IN DA-]PX TO THE REACTION-MECHANISM AND RELATIVISTIC EFFECTS

A method for the analysis of interactions between fast deuterons and nucleons is developed, taking into account both the relativistic effects in the deuteron and the mechanism of their interaction. The inclusive proton spectra and the polarisation characteristics are investigated, taking for instance the fragmentation type processes of deuterons on nucleons. A strong sensitivity of the deuteron polarisation tensor component T20 both to the reaction mechanism and to the relativistic structure of the deuteron is shown. It is shown that there can't be a direct indication of the 6q-state existence in the deuteron from the T20 experimental data. © 1990 Springer-Verlag.
