Proton Reactions of 238U in the 5-12 MeV Range

“…The agreement of our value of 5.7 mb at 11.5 MeV with the value of Ageev et al [1] of 4.5±0.9mb at 11 ±2 MeV is adequate. Our lower values at lower energies may be due to the better energy resolution in the present work.…”

“…The cross section between 7 and 30 MeV has been determined by Ageev et al [1] with approximate values of 3.0±1.5mb at 7±2 MeV rising to 8.8±1.1 mb at 29. 6 MeV.…”
