The electron capture of Lu/sup 173/ (1.30 yr) to levels in Yb/sup 173/) was investigated using scintillation spectrometers and permanent magnet spectrographs. Levels in Yb/sup 173/) were observed at 78.7 (7/2-), 179.5 (9/2- ), 351.2 (7/2+), and 636.8 (7/2-) kev. The first two excited states may be interpreted as members of a rotational band based on the ground state STA(512) 5/ 2-!. The levels at 351 and 637 kev are probably the intrinsic levels STA(633) 7/ 2+! and STA(514) 7/2-!, respectively, predicted by Nilsson. L electron capture was observed to be the primary mode of pepulation of the 637-kev level. Relative reduced transition probabilities were obtained for all transitions to the ground- state rotational band, and comparisons with theoretical branching ratios were made. Log(ft) values were estimated from the observed K-capture branching ratios. (auth)
