“…[33] with a very weak population and very large uncertainties on the reported cross-sections. This state overlaps in energy with the first 5 − state at 4367.0(4) keV reported in the evaluated data [31]. A peak at 4368(3) keV observed in this work is in excellent energy agreement with this reported 5 − state, and demonstrates relatively good agreement with the L = 5 transfer shown in Fig.…”

“…The agreement (or disagreement) with the evaluated 0 + -state data in Ref. [31] is discussed on a level-by-level basis below.…”

“…Due to the extremely large negative reaction Q-value for 52 Cr(p, t), no stable target was suitable for energy calibration. Instead, outgoing triton energies were benchmarked to 50 Cr excitation energies using well-known states from the evaluated data [31]. To further improve the accuracy and precision of the calibration, the triton energy dependence as a function of position from this work and Refs.…”

“…The compiled nuclear data in Ref. [31] reports five excited 0 + states in 50 Cr from the three previous 52 Cr(p, t) 50 Cr experiments [32][33][34], two of which were performed more than 40 years ago. With significantly improved resolution and sensitivity compared to these previous measurements, only two excited 0 + states in 50 Cr were definitively observed in the work presented here: 3895.0(5) keV and 4068.8(5) keV, while a third excited 0 + state at 4733(5) keV is also plausible.…”

Comparison of CdZnTe neutron detector models using MCNP6 and Geant4

“…Geant4 Figure 6 shows the γ-spectrum resulting from the interaction of neutrons from a 252 Cf source and a CdZnTe detector. The details of the peaks in the spectrum are described in table III; the γ-rays resulting from the de-excitation of the most common cadmium, zinc, and tellurium have been wellcharacterised, as described in the relevent Nuclear Data Sheets [13], [27], [29], [30], [31], [32], [33], [34], and the results presented here are in agreement with the energies of the most prominent of these γ-rays.
