We have developed fast scintillation detectors for nuclear resonant scattering experiments using synchrotron radiation and a nuclear excited level existing in >30 keV. A fast x-ray detector using an organic-inorganic perovskite scintillator of phenethylamine lead bromide (PhE-PbBr 4 ) had a dominant light emission with a fast decay time of 9.9 ns. An x-ray detector equipped with a 0.9-mm-thick PhEPbBr 4 crystal (size: ∼8 × 7 mm 2 ) was used to detect nuclear resonant scattering in 61 Ni (the first excited level: 67.41 keV; half-life: 5.3 ns). We could successfully record the decaying gamma rays emitted from 61 Ni with a relatively high detection efficiency of 24%. A lead-doped plastic scintillator (NE142, Pb ∼5 wt% doped) had been known to have a faster decay time of 1.7 ns. Following a test of a single NE142 detector, a four-channel NE142 detector was fabricated and successfully applied to the synchrotron-radiation based Mössbauer spectroscopy experiment on 61 Ni.

“…It is no surprise, however, that the accuracy of the fit would be reduced as a wider range of the ADC is included [16]. Luckily the majority of 127 Sb lines have energies that fall within this range; the most significant lines with lower energies sit at 290.8, 252.4, and 61.1 keV [11], but those values seem to be consistent with our rough energy calibration of the whole spectrum obtained using a simple linear function.…”

“…Through the study of various γ-ray spectra recorded from fission samples, it has been noticed that a few of the very strongest 127 Sb decay lines seem to have energies that significantly deviate from the evaluated values tabulated in Refs. [11,12]-by as much as 1 keV or more. This paper reports on one of those experiments and provides updated γ-ray energies and intensities corresponding to 127 Sb decay.…”

With a half-life of 3.85(5) days, the fission product 127 Sb is potentially useful for the characterization of fallout debris that would be collected for forensic analysis following a hypothetical nuclear event. The β decay of 127 Sb has many characteristic γ-ray lines, however the majority of decay strength is concentrated in the three strongest lines near 686, 473, and 784 keV, based on lowprecision spectroscopic measurements from decades ago. In a new measurement of 127 Sb β decay, obtained from radiochemical separations of U photofission products, we show that the energies of the 686 and 784 lines are actually shifted lower by 0.8 and 1.1 keV, respectively. Such large discrepancies in the nuclear data inhibit accurate isotopic analyses and have important implications, for example, on the assessment of fission debris that might be collected in the days following a nuclear event. Therefore, a new evaluation of 127 Sb β decay and appropriate revisions to the various nuclear databases are warranted. This paper reports a new set of γ-ray energies and relative intensities corresponding to 127 Sb decay.
