H. Miyahara et al., PRECISE MEASUREMENT OF THE EMISSION PROBABILITIES FOR THE WEAK 161 AND 223 KEV GAMMA-RAYS OF BA-133, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 374(2), 1996, pp. 193-196
Emission probabilities for the 160.6 and 223.2 keV gamma-rays of Ba-13
3 were measured by using a 4 pi beta(ppc)-gamma(HPGe) coincidence syst
em. Determined emission probabilities are 0.006383+/-0.000038 and 0.00
4530+/-0.000031, respectively. This implies that the relative accuracy
in the emission probabilities has been considerably improved in compa
rison with previous measurements.
