The study which is currently being pursued is an attempt to understand the mechanism of heavy-ion formation. The specific questions proposed to address were: are some heavy-ion combinations, leading to the same excitation energy range in the same compound nucleus, less likely to form resonances than others and, if so, to what extent; (2) to what extent do they form the same resonances. These questions are studied by forming, over a large range of excitation energies, the same compound nucleus through a number of different heavy-ion entrance channels. The compound nucleus, /sup 23/Na, was chosen since four stable target-projectile configurations (/sup 12/C + /sup 11/B, /sup 13/C + /sup 10/B, /sup 9/Be + /sup 14/N, and /sup 16/O + /sup 7/Li) could be used to form this compound nuclus. In addition, the /sup 12/C + /sup 11/B and /sup 7/Li + /sup 16/O systems are, according to classical calculations, dynamically well matched so that both entrance channels will reach the same compound nucleus excitation energy with approximately the same entrance channel angular momentum (a similar situation exists for the /sup 13/C + /sup 10/B and /sup 9/Be + /sup 14/N systems). Progress is reported. (WHK)
