Description
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 enrgies 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. (author)
