Description
The Lohengrin spectrometer was used for an on-line detection of neutron precursors with a half-life longer than 0.2 sec. Seven new isotopes were discovered: 91Se, 94Kr, 99Sr, 99Y, 134Sn, 137Te and 138Te. The half-lives were measured and the neutron emission probability written in % of the total β decay of the precursor nucleus
Abstract (French)
On a utilise le spectrometre Lohengrin pour la detection -en ligne- des precurseurs de neutrons de periode superieure a 0,2 sec. On a decouvert sept nouveaux precurseurs: 91Se, 94Kr, 99Sr, 99Y, 134Sn, 137Te et 138Te. On a mesure les periodes et la probabilite d'emission de neutrons exprimee en % de la desintegration β totale du noyau precurseurFiles
