(p, n) and (p, 2n) cross sections of nine elements between 7.0 and 15.0 MeV

Emission of alpha particles in the interaction of 10?85 MeV protons with48,50Ti

“…A second possible explanation for the discrepancy is purely experimental. The work of Chodil [17] on the SlV(p,2n) reaction suggests the likelihood of a very sharply defined peak. The present experiment performed in the internal circulating beam of the McGill Synchrocyclotron may not sample a narrow enough proton energy range to clearly define a peak at 20MeV.…”

Recommended nuclear data for medical radioisotope production: diagnostic gamma emitters

“…1 are also compared with equivalent TENDL-2015 and TENDL-2017 calculations. Ten datasets were rejected (Tanaka and Furukawa [22] (values too low), Albouy et al [24] (values too high), Hontzeas and Yaffe [28] (energy shift), Chodil et al [33] (values too high), Mehta et al (a) [36] (energy shift above 10 MeV), Stück [40] (data in energy range not included in fit), Kailas et al (b) [41] (energy shift), Michel et al [42] (data in energy range not included in fit), Bastos et al [43] (values too high), and Musthafa et al [47] (values too low)), and the remaining twenty-two sets were used in the statistical fitting procedure. These selected data and their experimental uncertainties are shown in Fig.…”

Studies of Flerovium and Element 115 Homologs with Macrocyclic Extractants

“…The Hg behavior was assessed by gamma spectroscopy of the 197m Hg (Eγ=133.99 keV, t1/2=23.8 h) isotope [208]. Due to the scattered neutrons (produced in the (p,n) reaction) at the target chamber, 198 Au (Eγ=411.80 keV, t1/2=2.70 d) was also produced via the 197 Au(n,γ) 198 Au reaction which yielded a convenient tracer for quantifying the Au content in the elution fractions [208]. Figure 45 shows the gamma spectra of the irradiated Au foil and the As can be seen in Figure 46, both Au and Hg have strong uptake at the load condition of 1 M HNO3, but Hg extraction is negligible above 10 M HNO3 while Au is still strongly sorbed up to ~13 M HNO3.…”

“…Typical tracers produced for this work utilized proton-bombardment reactions on stable target materials; however, heavier charged particles such as helium can also be used. The In(p,n) 113 Sn reactions have been reported in literature, separation methods of carrier-free activity from the Sn, Au, and In target materials are lacking [197][198][199].…”
