THE CROSS SECTION FOR COMPOUND-NUCLEUS FORMATION IN HEAVY-ION-INDUCED REACTIONS

摘要

Compound-nucleus-formation cross sections for various systems of heavy ions and targets have been calculated by using two simple models. The first model, based on a square-well nuclear potential, gives reasonable agree¬ment with experiment if a radius parameter ro ≌ 1.5 fermis is used. The second model, based on a diffuse nuclear potential, gives agreement if r =1.17 fermis is used. The cross sections calculated by using the first model are presented for various energies of the systems carbon, nitrogen, oxygen, and neon incident on aluminum, potassium, copper, silver, praseodymium, gold, and uranium. Also tabulated are the average values of the orbital angular momentum for each system at each energy.
