“…Finally, we compare the measured PFGS at excitation energy of 6.5 MeV, which corresponds to the thermal Pleasonton (1973) [30] and Verbinski et al (1973) [11] are shift slightly around Sn for better visibility. Multiplicity, average γ-ray energy, and total γ-ray energy, as function of excitation energy of 240 Pu* are shown.…”

Future research program on prompt $\gamma$ -ray emission in nuclear fission

“…There are several studies on spontaneous fission of 252 Cf [15] and thermalneutron-induced fission on 235 U [15][16][17], 233 U [17,18] and 239 Pu [15,18]. The energy range for γ-rays was extended down to 10 keV [16] and up to 8 MeV.…”

Prompt particle emission in fission – news on systematics and predictions for fission induced by fast neutrons

“…[28] and a quadratic fit to the latter [17], with good agreement within the uncertainties. To date experimental data are only available for neutrons of some keV energy and thermal neutrons and depicted by open (blue) squares [13,15], and open and closed (orange) diamonds [32,33], respectively. The agreement is rather good (with the exceptions mentioned above), although the evaluation does not exhibit the same pronounced thresholds for multiple chance fission.…”

“…Here the few available experimental data at thermal energies from Refs. [32,33] (open and closed orange diamonds) and in the keV region [13,15] (open blue squares) are complemented by the result of an evaluation [28] and a quadratic fit to the latter [17], depicted as open (purple) triangles and dotted (brown) line, respectively. which has been confirmed by calculations within the Pointby-Point model, where corresponding results are available.…”
