General Comments:

Double Beta Decay: With a Q(2β-)=825.4 9, it is possible that 134Xe decays to 134Ba through 2β-. The table below lists experimental T1/2 upper limits for different decays modes. Results from 1989Ba22, an earlier version of 1990Ba22, are not listed.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(2β-)=825.4 9 (2003Au03)

  2136.60   In 1969Wi16, the level scheme was built with the 405-keV γ and the 217-keV γ depopulating the same level. In 2001Ge07, however, the γ-rays in coincidence with the 405 γ are not in coincidence with the 217 γ. As a consequence, the adopted level scheme is built assuming they originate from 2 different levels, very close in energy.
