A semiquantal theory of Coulomb fission is presented; it is shown that Coulomb fission is essentially a two-step process: multiple Coulomb excitation of an actinide target nucleus by a heavy projectile ( Z p 3 50) followed by radioactive decay. The coupledchannels Coulomb excitation calculations involve a large set of collective energy levels (-260) and reduced ME2 matrix elements (-8300) which are calculated from the extended rotation-vibration model. The spin-zero fission potential is based on barrier param…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
