Photoproduction of neutral pions on deuterons at the first resonance

Creators

Description

The π0 generated by bremsstrahlung was determined by its decay quanta in two Cherenkov counters. Simultaneously, coincident nucleons were measured by a proton-and-neutron-sensitive second counter arm. Kinematically, the ratio of neutron and proton cross section was sensitive to a possible isotensor component in the electromagnetic current. The ratio between isotensor and isovector amplitude was found to be 0.02 +- 0.04. (BJ)

Abstract (German)

Das von einem Bremsstrahl erzeugte π0 wurde ueber seine Zerfallsquanten in zwei Cherenkovschauerzaehlern nachgewiesen und gleichzeitig ein fuer den Nachweis von Protonen und Neutronen empfindlicher zweiter Arm nach koinzidenten Nukleonen abgefragt. Die Kinematik wurde so ausgewaehlt, dass das Verhaeltnis der auf Neutron bzw. Proton bezogenen differentiellen Wirkungsquerschnitte empfindlich auf einen moeglichen Isotensoranteil im elektromagnetischen Strom war. Fuer das Verhaeltnis von Isotensor- zu Isovektoramplitude wurde ein Wert von 0,02 +- 0,04 gefunden. (BJ)
