By use of pulse NMR methods, the temperature dependences of the longitudinal and transverse relaxation times for (1)H and (19)F were measured for the three phases of 1-butyl-1-methylpiperidinium bis(fluorosulfonyl)amide ([Pip1,4][FSA]), i.e., liquid or supercooled liquid, Cryst-α, and Cryst-β, to...

Determination of the emission probabilities of the principal gamma-rays for 134Cs to a high precision.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Miyahara H, Hayashi N, Fujiki K, Takeuchi N, Hino Y.

Appl Radiat Isot. 2002 Jan-Feb;56(1):131-5. doi: 10.1016/s0969-8043(01)00178-6.

While multi-gamma-ray emitting nuclides such as 75Se, 134Cs and 152Eu have reasonably well-defined decay scheme, some inconsistencies still remain. Detailed evaluations and weighted-mean analyses result in the recommendation of gamma-ray emission probabilities with small uncertainties, although significant deviations exist...
