Identification of new neutron-rich rare-earth nuclei produced in /sup 252/Cf spontaneous fission
A program of systematic study of the decay properties of neutron-rich rare-earth nuclei with 30 s<t/sub 1/2/<10 min, produced in /sup 252/Cf spontaneous fission, is currently underway using the Idaho ESOL (Elemental Separation On Line) Facility. The chemistry system used for the rare-earth ele...

description | A program of systematic study of the decay properties of neutron-rich rare-earth nuclei with 30 s<t/sub 1/2/<10 min, produced in /sup 252/Cf spontaneous fission, is currently underway using the Idaho ESOL (Elemental Separation On Line) Facility. The chemistry system used for the rare-earth elemental separations consists of two high-performance chromatography columns connected in series and coupled to the /sup 252 /Cf fission source via a helium gas-jet transport arrangement. The time delay for separation and initiation of gamma -ray counting with results which have been obtained to date with this system include the identification of a number of new neutron-rich rare-earth isotopes including /sup 155/Pm (t/sub 1/2/=48+or-4 s) and /sup 163/Gd (t/sub 1 /2/=68+or-3 s), in addition to 5.51 min /sup 158/Sm which was identified in an earlier series of experiments.
