Study of the 157Tm (Tsub(1/2)=3.3 min) and 155Tm (Tsub(1/2)=25 sec) decays
Description
The level structures of the N = 89 157Er and N = 87 155Er nuclei have been investigated through the decay of 157Tm (Tsub(1/2) = 3.3 min) and 155Tm (Tsub(1/2) = 25 s). Mass separated samples were obtained from the ISOCELE 1 on-line separator. Gamma ray spectra, conversion electron spectra and γ-γ bi-dimensional coincidences were examined, and lead to proposed level schemes for these transitional nuclei
Abstract (French)
Nous avons étudié les décroissances β+ + CE de 157 Tm (T1/2 = 3,3 min) et 155Tm (T 1/2 = 25 s) sur les niveaux de 157Er (N = 89) et 155Er (N = 87). Les sources isotopique-ment pures ont été obtenues grâce au séparateur ISOCELE 1 en ligne avec le synchrocyclotron d'Orsay. L'étude des spectres gamma, des spectres d'électrons de conversion et des coïncidences bidimensionnelles γ-γ a permis de proposer des schémas de niveaux pour ces noyaux de la zone de transition.Additional details
