Abstract
The low-energy portion of the photon spectrum for the ..beta.. decay of /sup 2/34Th has been investigated with a carefully calibrated Ge(Li) detection system because of the excessive photon intensity of the M1 73.7-keV transition reported previously. The new photon intensity obtained for this transition relative to other strong transitions is consistent with the most recent conversion electron measurements in the two-step /sup 2/34Pa/sup m/ isomeric transition. The upper energy limit of the unobserved E3 isomeric transition is discussed in terms of total converion coefficients, hindrance factors, and the detection limit of the recent conversion electron measurements.
