Abstract
The final set of results of ''ground-state'' beta(-)-branching intensi ties obtained in a program of systematic study of those regions of the fission-product nuclides accessible to investigation using the Cf-252 -based INEL ISOL facility are presented. A total absorption gamma-ray spectrometer, operating in a 4 pi gamma-beta coincidence mode, was use d to obtain these ''ground-state'' beta(-)-branching intensities; wher e here the ''ground-state'' is defined to include all states below a s elected gamma-ray discriminator level. Results obtained for Rb-89, Rb- 90g, Rb-91, Rb-93, Sr-93, Sr-94, Y-94, Sr-95, Y-95, (CS)-C-140, La-142 , Ba-143, La-143, Ba-144, La-144, Ba-145, La-145, Ce-146, (146)pr, Ce- 147, Pr-147, Ce-148, Pr-148 (2.27 min), Pr-149, Nd-149, Pr-151, Nd-151 , Pm-152 (4.1 min), Nd-153, Nd-155, Pm-157, Sm-157,Sm-158 and Eu-158 a re presented and compared with existing published data.
