Measurements of mean reaction times for fusion-fission and fusion-evaporation processes in the 28Si+28Si interaction.

Axial and planar blocking patterns in thin Si single crystals have been measured for the products of the reaction {sup 28}Si(150 MeV)+{sup 28}Si at {theta}{sub {ital L}}=15{degree} and 12{degree}. Reaction times of the order 10{sup {minus}18--}10{sup {minus}17} s have been observed for fusion-evaporation and fusion-fission processes.
