Fission decay of highly excited periodically driven compound nuclei is considered in the framework of the Langevin approach. We used residual-time distribution (RTD) as a tool for studying dynamic features in the presence of periodic perturbation. The structure of RTD essentially depends on the relation between Kramers’ decay rate and the frequency ω of periodic perturbation. In particular, the intensity of the first peak in RTD has a sharp maximum at certain nuclear temperature depending on ω. This maximum should be considered as first-hand manifestation of stochastic resonance in nuclear dynamics. © 2001 MAIK “Nauka / Interperiodica”.

    We extend the standard model by adding an extra generation of isosinglet up- and down-type quark pair which engage in weak interactions only via mixing with the three ordinary quark families. It is shown that the generalized 4 × 4 quark mixing matrix, which is necessarily nonunitary, leads...

    The mechanism in which two-plasmon decay (TPD) waves have to propagate in the density gradient of a laser-irradiated plasma in order to scatter (3/2)-harmonic photons is shown not to be able to explain most features of observed (3/2)ω0 spectra. Instead, a process of mode coupling of TPD to...

    A study is made of the decay instability of a lower hybrid wave with a finite wave vector (k[sub 0]≠0) and a large amplitude such that the oscillatory velocity of the electrons with respect to the ions cannot be neglected. It is shown that, depending on the angle between the propagation...
