Description

Results on the reaction ep → e'nπ+ are presented in the mass range W between 1.355 and 1.775 GeV at q2 = 1 GeV2 and in the range from 1.415 to 1.595 GeV at q2 = 0.6 GeV2. From the angular distribution of the π+ meson the polarization terms sigma(u) + epsilon sigma(L), sigma(p) and sigma(I) have been determined in the range of production angles theta(π+) from 0 to 630. (orig.)

Abstract (German)

Angegeben werden die Ergebnisse der Reaktion ep → e'nπ+ in dem Massenbereich W zwischen 1,355 und 1,775 GeV bei q2 = 1 GeV2 und zwischen 1,415 und 1,595 GeV bei q2 = 0,6 GeV2. Aus der Winkelverteilung der π+-Mesonen wurden die Polarisationsterme sigma(u) + epsilon sigma(L), sigma(p) und sigma(I) im Produktionswinkelbereich theta von 0 bis 630 bestimmt. (orig./WL)
