Detection of hard photons with BaF2 scintillators

Hard-photon emission inXe129+197<

“…By assuming as an analytical expression) of AE'/E =0.12, in reasonable agreement with both the experimental and simulated data [15]. We note that the BNV calculation taking into account the radiation from virtual charged pion exchange, although providing a reasonable value of the overall p yield, overestimates the inverse slope parameter by a factor 1.2.…”

Exploiting Cross-Luminescence in BaF2 for Ultrafast Timing Applications Using Deep-Ultraviolet Sensitive HPK Silicon Photomultipliers

“…Furthermore, it is not hygroscopic, unlike for example CsF. Therefore, after its discovery there has been an enormous interest in BaF 2 , and numerous research groups started investigating this material [5,12,14,[20][21][22][23][24], both to understand its characteristics and to use it in detectors incorporating time-offlight information. Table 1 shows an overview of the characteristics of BaF 2 , as well as those for LYSO and BGO for comparison.…”

Simultaneous measurements of (p→, p→′) and (Wells1, Wissink2, Bacher3 et al. 1995Phys. Rev. C

“…Following the method of Novotny et al [32], we first used the correlation between the fast component of the scintillator response and the total light output to discriminate between neutral particles and charged particles (top figure). We then looked at the relative timing between the detection of the protons in the K600 focal plane and the neutral particles in the BaF2 detectors, in order to separate the prompt y rays from the time-uncorrelated neutrons (middle figure).…”
