Description

Isotopes 130Nd and 140Tb were produced using enriched targets 96Ru and 106Cd, respectively, bombarded by 36Ar ion beam. The two nuclides were identified and studied by a He-jet tape transport system in combination with 'X-γ' and 'γ-γ' coincidence measurements. The half-life of 130Nd was determined to be (13 +- 2)s. The EC/β+ decay scheme of 130Nd was proposed for the first time, and the spins and parities of the ground-state and observed low-lying states in the daughter nucleus 130Pr were speculated tentatively. The previous simple EC/β+ decay scheme of 140Tb was revised, and the spin-parity of its ground-state was assigned to be 7+
