γ−γDirectional Correlations in the Decay ofSb125

Self-consistent measurements of angular correlation of the 321–177 and 204–177 keV cascades in 125Te

“…For the 321-177 keV cascade the value of D 5 measured by us is found to be in good agreement with the result reported by Wyly et al [9]. The results reported by Knapek et al [4], Cruse et al [6] and Inamura et al [7] are close to the present measured value.…”

“…Cruse et al [6], Inamura et al [7], and Singh et al [8] using a NaI(Tl)-NaI(Tl) detector system obtained D 5 values that agree within experimental error. On the other hand, Rots et al [5] and Wyly et al [9] using a Ge(Li)-NaI(Tl) detector system, obtained higher values of D 5 . The present value of D 5 @ 3=7:4 3=344 measured by a high-resolution HPGe-HPGe detector system lies in between the two sets of values given above.…”

“…From these measurements the values of E+H5, and E+P 4, are expected to be determined more accurately through the measured values of and thus help to settle the original question raised by Kisslinger: Is the negative-parity triplet an excitation of three quasiparticle coupling or does it arise from a single k 44@5 neutron coupled to a phonon excitation? The angular correlation measurements on the 321-177 and 204-177 keV cascades passing through the 321 and 525 keV levels were performed earlier [4][5][6][7][8][9][10][11] (Table 1). From these measurements the values of the 321, 177, and 204 keV transitions were reported.…”
