Description

The (π-,2n) reaction on 40Ca has been investigated via the determination of the momenta for the two neutrons emitted simultaneously following the absorption of π-. The 38K excitation spectrum, opening-angle distributions, and recoil momentum distribution are determined. The direct mechanism is established for transitions to the lower part of the 38K excitation spectrum. (orig.)

Abstract (German)

Die (π-,2n) Reaktion an 40Ca wurde durch die Bestimmung der Impulse der beiden gleichzeitig in Folge der Absorption von π- emittierten Neutronen untersucht. Es wurden das Anregungspektrum von 38K, Oeffnungswinkelverteilungen und die Rueckstossimpulsverteilung bestimmt. Der direkte Mechanismus wird fuer Uebergaenge zum tieferliegenden Teil des Anregungsspektrums von 38K erstellt. (orig.)
