Non Trivial Effects in Heavy Nuclear Systems due to Charge Rearrangement

Abstract

In this report we propose that a charge rearrangement within heavy ions may occur during fusion reactions, lowering the Coulomb barrier as the nuclear systems approach each other. In this situation a modified Gamow factor has been calculated, which emphasizes the importance of spatial degrees of freedom in nuclear matter.
