Nuclear stochastic resonance

Fission decay of highly excited periodically driven compound nuclei is cons idered in the framework of the Langevin approach. We used residual-time dis tribution (RTD) as a tool for studying dynamic features in the presence of periodic perturbation. The structure of RTD essentially depends on the rela tion between Kramers' decay rate and the frequency omega of periodic pertur bation. In particular, the intensity of the first peak in RTD has a sharp m aximum at certain nuclear temperature depending on omega. This maximum shou ld be considered as first-hand manifestation of stochastic resonance in nuc lear dynamics. (C) 2001 MAIK "Nauka/Interperiodica".
