Various processes occurring in strong interactions between heavy ions: Compound nucleus formation, incomplete fusion, and quasifission

This paper deals with the problem of various deep processes occurring when two complex nuclei enter in collision. It is suggested that very deep inelastic processes may lead to either a compound nucleus or a composite system which shortly decays into two fission fragments (quasifission process). Particularly for heavy projectiles and targets, the predominant Coulomb potential inhibits the compound nucleus formation for low $l$ waves. Then a critical angular momentum can be defined as the limit below which both processes (quasifission and compound nucleus formation) occur. For the heaviest nuclei, nearly all $l$ waves below $l_{\mathrm{cr}}$ contribute to the quasifission phenomenon.
