“…The intensity of the 315-keV transition between the 1866-keV 4 + level and the 1551-keV 2 + level can be set at a value of no greater than 6 per 105 decays or a branching ratio of <8 x 105. In a purely vibrational model this "zero phonon" transition is forbidden, However, evidence has been given for such a transition in 6~ [19]. Further, the large splitting of the phonon triplet indicates a strictly vibrational model should not be applied here.…”

“…For ~3~Ba, Stelson etal. [10], and is in contrast to the zero-phonon transition ratio of 29+5 observed [25] in 6~ However, the large splitting of the second phonon triplet and other levels below 2 MeV must also be considered. In this work we have been able to set a new limit of 905 for this ratio by using the LLL Compton-suppression spectrometer [7].…”

A precision study of the decay of 134CSg and ~ 34Cs" has been made, using ordinary Ge(Li) spectrometers and a Compton-suppression spectrometer. The logft value of the second forbidden nonunique fl-decay to 134Xe has been measured to be 13.0_+0.2. The M4 7-ray transition in 13~Csm(8-) decay has been measured to have c~K= 73 + 7 and a hindrance of 7.0 over the Moskowski estimate. This is discussed in terms of the level configurations and the analogous transition in ~33Xe. A new intensity limit of 2 x 10 -6 has been set for the zero-phonon transition between the 4 + and 2 + members of the two-phonon triplet. This leads to an upper limit for B(E2)4~2, greater than 905. This and the more precise 7-ray intensity values are discussed in relation to presently available nuclear models.Radioactivity 134Cs and ~34Csm. Measured E~, I~,, 134Ba, 13'~Cs deduced levels.
