Preparation and characterisation of an {39}Ar sample and study of the {39}Ar(nth,alpha){36}S reaction

Project ID: 1993
Funded under: FP5-JRC

Abstract

The {39}Ar(nth,alpha){36}S reaction has been studied for the first time. A sample containing 2.85×10{14} {39}Ar atoms was produced at the ISOLDE facility at CERN. The number of {39}Ar atoms in the layer was determined by measuring the [39}Ar beta-activity using a primary standardisation method. Subsequently, the sample was irradiated with thermal neutrons at the High Flux Reactor of the Institut Laue�Langevin. An upper limit of 0.29 b was obtained for the {39}Ar(nth,alpha){36}S reaction cross-section.
