Characteristics of Coulomb fission
Hans Kruse and William T. Pinkston Department of Physics, Vanderbilt Uniuersity, Nashuille, Tennessee 37235 (Received 23 February 1979) Within an extended semiquantal theory we perform large-sized coupled-channel calculations involving 260 collectiue .levels for Coulomb fission of 238U. Differential Coulomb fission cross sections are studied as a function of bombarding energy and impact Paramet...
متن کاملA genetic algorithm-based approach for numerical solution of droplet status after Coulomb fission using the energy
As a droplet moves, due to evaporation at the surface, the droplet size is gradually reduced. Due to decreasing the size of the droplets moving in the spray core, the surface charges become closer and the repulsive force between the charges increases. When the Coulombic force overcomes the surface tension force (Rayleigh instability) the droplet breaks into smaller droplets (Coulomb fission). T...
متن کاملFission-Fusion Dynamics:
Nineteen scientists from different disciplines collaborated in highlighting new methodological and theoretical aspects in the re-emerging study area of fission-fusion dynamics. The renewed interest in this area is due to the recognition that such dynamics may create unique challenges for social interaction and distinctive selective pressures acting on underlying communicative and cognitive abil...
متن کاملCoulomb fission in multiply charged molecular clusters: Experiment and theory.
A series of three multiply charged molecular clusters, (C6H6)nz+ (benzene), (CH3CN)nz+ (acetonitrile), and (C4H8O)nz+ (tetrahydrofuran), where the charge z is either 3 or 4, have been studied for the purpose of identifying the patterns of behaviour close to the charge instability limit. Experiments show that on a time scale of ∼10-4 s, ions close to the limit undergo Coulomb fission where the o...
متن کاملFission dynamics within time-dependent Hartree-Fock: Boost-induced fission
Methods: Following upon the work presented in Ref. [1], quadrupole-constrained Hartree-Fock calculations are used to create a potential energy surface. An isomeric state and a state beyond the second barrier peak are excited by means of instantaneous as well as temporally extended gauge boosts with quadrupole shapes. The subsequent deexcitation is studied in a time-dependent Hartree-Fock simula...
