Levinger's modified quasi-deuteron model has been used to analyse available experimental data on total nuclear photoabsorption cross-section in the mass range 7 ⩽ A ⩽ 238 and in the energy range (35 ÷ 140) MeV. It is shown that the measured cross-sections are successfully reproduced by the formula σT(Eγ) = LNZ/AσD(Eγ) exp [- D/E] with L = 6.1 ± 2.2 and D = 0.72A0.81.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
