Technique for sequential Cherenkov and liquid scintillation counting after concentration of emitters on submilligram amounts of carrier

Technique for sequential Cherenkov and liquid scintillation counting after concentration of emitters on submilligram amounts of carrier. Bates, T. H. (Windscale Calder Works, Br. Nucl. Fuels Ltd., Sellafield/Seascale/Cumbria, Engl.). Liq. Scintill. Counting, 4, 142-51 (English) 1975. CODEN: LQSCAP. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) Section cross-reference(s): 79 A simple technique is presented for concg. radiochem. sepd. Pu on sub-mg quantities of Y or Fe hydroxides, collecting the ppt. on a membrane filter, and transferring it to the scintillant. The final prepn. is homogeneous, and therefore susceptible to a quench correction. This technique was applied to 3 types of fission product, i.e. 90Y [10098-91-6], 144Ce [14762-78-8]-144Pr [14119-05-2] equil., and 95Zr [13967-71-0]-95Nb [13967-76-5] equil. The membrane and ppt. are 1st dispersed in pure solvent (dioxane) to study the Cherenkov gain spectrum, followed by the addn. of dioxane-based scintillant to study the scintillation spectrum. Advantages and potential applications of the technique are discussed.

Shell-model calculations of zirconium-90, -88 and yttrium-90, -88. Becker, J. A.; Bloom, S. D.; Warburton, E. K. (Lawrence Livermore Natl. Lab., Univ. California, Livermore, CA 94550, USA). ACS Symp. Ser., 324(Nucl. Off Line Stab.), 78-84 (English) 1986. CODEN: ACSMC8. ISSN: 0097-6156. DOCUMENT TYPE: Journal CA Section: 70 (Nuclear Phenomena) Conventional spherical shell model calcns. were undertaken to describe 90,88Zr and 90,88Y. In these large-scale calcns. valence orbitals included 1f5/2, 2p3/2, 2p1/2, and 1g9/2.There are some commonly used reagents with their cas registry numbers 13982-15-5 and 14681-75-5 in this article. The d5/2 orbital was included for 90Y [10098-91-6] and for high-spin calcns. in 90Zr [13982-15-5]. Restrictions were placed on orbital occupancy so that the basis set amounted to <25,000 Slater determinants. Calcns. were done with a local, state-independent, 2-body interaction with single Yukawa form factor. Predicted excitation energies and electromagnetic transition rates are compared with recent exptl. results. .
