Within the fragmentation theory, extended to include the orientations degrees of freedom and hexadecupole deformations, for optimized orientations, the {sup 48}Ca+{sup 244}Pu{yields}{sup 292}114* reaction is shown to be a 'compact' hot fusion reaction. The barrier is highest (hot fusion) and interaction radius smallest (compact), which occur for the collisions in the direction of the minor axis of the deformed reaction partner (i.e. for 90 deg. orientation of {sup 244}Pu). In addition to the {sup 48}Ca+{sup 244}Pu reaction valley, a number of other new reaction valleys (target-projectile combinations) are shown to arise for the 'optimally oriented hot' fusion process, the {sup 48}Ca+{sup 244}Pu being the best (lowest barrier) and {sup 54}Ti+{sup 238}U as the next possible best reaction for forming the cold compound nucleus {sup 292}114*. A similar reaction valley for {sup 48}Ca+{sup 244}Pu is found absent in the 'optimally oriented cold' fusion process.
