fissioning 
In addition to the main process of binary fission, three branches of collinear threebody disintegration, which are associated with various mechanisms of the excitation of a deformed fissioning nucleus, are observed.


The analysis performed reveals that the coordinateindependent reduction coefficient ks is not compatible with the simultaneous description of the main fission characteristics for fissioning systems heavier than 224Th.


It is emphasized that angular anisotropy and various angular correlations of fission products are possible only if the fissioning nucleus remains nonthermalized during all the stages of fission from the saddle point to scission.


In contrast to prompt neutrons, scission neutrons are expected to mostly depend on the characteristics of the fissioning nucleus and, in particular, on its neutron number N.


The analysis is done for five compound nuclear systems representing heavy fissioning nuclei, medium fissioning nuclei, and a light fissioning one with the angular momentum varied in a wide range from l = 0 to 70?.


It is concluded that in quaternary fission, as in ternary fission, light particles escape from the neck of the fissioning nucleus much earlier than scission of the nucleus into heavy fragments occurs.


The results obtained lead to the conclusion that in ternary fission charged particles are emitted by the fissioning nuclear system rotating around the polarization direction.

Conversely, the dominant metastable decay channel of Ar4+* into Ar2+ was found to proceed predominantly via a single step fissioning process.


The increase of the cutoff energy of (n, nf) reaction neutron spectra with excitation energy of fissioning nucleus is described.


To study saddle point states of fissioning nuclei in the singleparticle model nucleon wave functions and energylevels for highly deformed nuclei are needed.


The asymmetry of the fragment mass distribution of fissioning nuclei is described by suitable parametrization of an asymmetric twocenter shell model (ATCSM).


The derivation of?eff values has included corrections for the effects of incomplete fusion mechanisms on the orbital angular momentum distribution of the fissioning nuclei and for neutron evaporation prior to fission.


A fissioning nucleus is described by a Hamiltonian consisting of the kinetic energy, of a single particle potential depending on an arbitrary deformation parameter and of the pairing force.


We calculate the nonadiabatic excitations of pair states in a BCS formalism for a fissioning236U nucleus.


We bombarded natural uranium targets with lead ions and searched for alphaemitting and spontaneously fissioning reaction products.


We have deduced the linear momentum transferred from the projectile to the fissioning nucleus in the reaction20Ne+197Au at 30 MeV/A by measuring the folding angle between the two fission fragments.


A search for an unknown spontaneously fissioning activity, possibly due to SHE, was carried out with the Dubna3Hecounter system.


TheJrms derived from isomer ratio data in all thermal fissioning systems indicate a wide spread ranging from 2? to 13?.


The FokkerPlanck equation for the distribution function of collective variables is used as a dynamical equation to describe the descent of the fissioning nucleus from the saddle to scission.
