Tidskriftsartikel (refereegranskat)abstract
- γ-singles and γ-γ coincidence measurements have been performed on samples of 143La produced in thermal neutron induced fission of 235U. The nuclide was isolated by means of the on-line chemical separation system SISAK in combination with a gas jet recoil transportation (GJRT) system. From the decay of the strongest γ-lines, the half-life of 143La has been determined to be 14.23 ± 0.14 min. A number of new γ-rays are reported, and a decay scheme involving many new levels has been derived.

Decay Properties of 144-146La

Ingår i: J. Inorg. Nucl. Chem. - : Elsevier BV. ; 39, s. 1487-1493
-
Tidskriftsartikel (refereegranskat)abstract
- γ-ray singles and coincidence measurements have been performed on the neutron-rich nuclides 144La, 145La and 146La, produced in thermal neutron-induced fission of 235U. The studies were facilitated by the combination of a gas jet recoil transportation (GJRT) system with the rapid on-line chemical separation system SISAK. Half-lives of 42.1±0.7 s, 25.2±2.6 s and 8.5±1.0 s were obtained for 144La, 145La and 146La, respectively. Several new γ-ray energies have been assigned to each of the nuclides, and partial decay schemes are proposed for 144La and 146La together with a preliminary partial decay scheme for 145La.

Decay Properties of some Neutron-rich Cerium Isotopes

Ingår i: J. Inorg. Nucl. Chem.. - : Elsevier BV. ; 39, s. 1929-1934
-
Tidskriftsartikel (refereegranskat)abstract
- γ-γ-coincidence measurements have been performed on neutron-rich Ce isotopes using the fast radiochemical separation system SISAK in combination with a gas jet recoil transportation system. The results include assignments of new γ-rays and proposal of partial decay schemes for 3 min 145Ce, 56 s 147Ce and 48 s 148Ce. The existing decay scheme of 14 min 146Ce has been verified, except for a few transitions.
