Nucleon transfer in symmetric heavy-ion reactions at energies below the Coulomb barrier is investigated in the framework of a microscopic stochastic mean-field theory. Although mean field alone is known to significantly underpredict the dispersion of the fragment mass distribution, a considerable enhancement of the dispersion is obtained in the stochastic mean-field theory. The variance of the fragment mass distribution deduced from the stochastic theory scales with the number of exchanged nucleons. Therefore, the new approach provides the first fully microscopic theory consistent with the phenomenological analysis of the experimental data.

Quantal description of nucleon exchange in a stochastic mean-field approach
Ayik, S.; YILMAZ TÜZÜN, ÖZGÜL; YILMAZ, BÜLENT; Umar, A. S.; GÖKALP, AHMET; Turan, Gürsevil; Lacroix, D. (2015-05-04)
The nucleon exchange mechanism is investigated in central collisions of symmetric heavy ions in the basis of the stochastic mean-field approach. Quantal diffusion coefficients for nucleon exchange are calculated by including non-Markovian effects and shell structure. Variances of fragment mass distributions are calculated in central collisions of Ca-40 + Ca-40, Ca-48 + Ca-48, and N-56 i+ Ni-56 systems.
Multinucleon transfer in central collisions of U-238+U-238
Ayik, S.; YILMAZ, BÜLENT; YILMAZ TÜZÜN, ÖZGÜL; Umar, A. S.; Turan, Gürsevil (2017-08-14)
Quantal diffusion mechanism of nucleon exchange is studied in the central collisions of U-238 + U-238 in the framework of the stochastic mean-field (SMF) approach. For bombarding energies considered in this work, the dinuclear structure is maintained during the collision. Hence, it is possible to describe nucleon exchange as a diffusion process for mass and charge asymmetry. Quantal neutron and proton diffusion coefficients, including memory effects, are extracted from the SMF approach and the primary fragm...
ELECTROINITIATED POLYMERIZATION OF BUTADIENE SULFONE
AYBAR, SP; HACIOGLU, B; Akbulut, Ural (1991-12-01)
Electroinitiated polymerization of butadiene sulfone was achieved by direct electron transfer in acetonitrile-tetrabutylammonium fluoroborate system by controlled potential electrolysis technique. High conversions were obtained at reasonable temperatures and polymerization times. The polymer was found to be composed of linear segments along with some cyclic units. The effect of monomer concentration, temperature, and polymerization potential on the rate of polymerization was investigated. Temperature an...
Spinodal instabilities in symmetric nuclear matter within a nonlinear relativistic mean-field approach
Acar, Fatma; Yılmaz, Osman; Department of Physics (2011)
Spinodal instability mechanism and early development of density fluctuations for symmetric nuclear matter at finite temperature are studied. A stochastic extension of Walecka-type relativistic mean-field model including non-linear self-interactions of scalar mesons with NL3 parameter set is employed in the semi-classical approximation. The growth rates of unstable collective modes are investigated below the normal density and at low temperatures. The system exhibits most unstable behavior in longer wave len...
Regioselectivity in the Ene reaction of singlet oxygen with cyclic alkenes and application of Ene reaction to stereoselective synthesis of carbaheptopyranose derivatives
Doğan, Şengül Dilem; Balcı, Metin; Department of Chemistry (2010)
In the first part of this thesis is related to the regioselectivity in ene reaction of singlet oxygen with cyclic alkenes. The photooxygenation of 1-methyl-, 2,3-dimethyl-, 1,4-dimethylcyclohexa-1,4-dienes, 1,2,3,4,5,8-hexahydronaphthalene (16) and 2,3,4,7-tetrahydro-1H-indene (17) which are readily available through Birch reduction, yielded the ene products. The formed endocyclic dienes were trapped by the addition of singlet oxygen to give corresponding bicyclic endoperoxy-hydroperoxides. In the case of 1...
