The multinucleon exchange mechanism in Ni-58 + Ni-60 and Ni-60 + Ni-60 collisions is analyzed in the framework of the stochastic mean-field approach. The results of calculations are compared with the time-dependent random-phase approximation (TDRPA) calculations and the recent data of Ni-58 + Ni-60. A good description of the data and a relatively good agreement with the TDRPA calculations are found.

Multinucleon exchange in quasifission reactions Ayik, S.; YILMAZ, BÜLENT; Yılmaz, Osman (2015-12-31) The nucleon exchange mechanism is investigated in the central collisions of Ca-40+U-238 and Ca-48+U-238 systems near the quasifission regime in the framework of the stochastic mean-field (SMF) approach. Sufficiently below the fusion barrier, a dinuclear structure in the collisions is maintained to a large extent. Consequently, it is possible to describe nucleon exchange as a diffusion process familiar from deep-inelastic collisions. Diffusion coefficients for proton and neutron exchange are determined from ...
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...
Pseudorapidity dependence of long-range two-particle correlations in pPb collisions at root sNN=5.02 TeV Khachatryan, V.; et. al. (2017-07-01) Two-particle correlations in pPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV are studied as a function of the pseudorapidity separation (Delta eta) of the particle pair at small relative azimuthal angle (|Delta phi| < pi/3). The correlations are decomposed into a jet component that dominates the short-range correlations (|Delta eta| < 1), and a component that persists at large Delta eta and may originate from collective behavior of the produced system. The events are classified in term...
Multipath Characteristics of Frequency Diverse Arrays Over a Ground Plane Cetintepe, Cagri; Demir, Şimşek (Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01) This paper presents a theoretical framework for an analytical investigation of multipath characteristics of frequency diverse arrays (FDAs), a task which is attempted for the first time in the open literature. In particular, transmitted field expressions are formulated for an FDA over a perfectly conducting ground plane first in a general analytical form, and these expressions are later simplified under reasonable assumptions. Developed formulation is then applied to a uniform, linear, continuous-wave opera...
Multidimensional quantum tunneling in the Schwinger effect Dumlu, Cesim K. (American Physical Society (APS), 2016-03-22) We study the Schwinger effect, in which the external field having a spatiotemporal profile creates electron-positron pairs via multidimensional quantum tunneling. Our treatment is based on the trace formula for the QED effective action, whose imaginary part is represented by a sum over complex worldline solutions. The worldlines are multiperiodic, and the periods of motion collectively depend on the strength of spatial and temporal inhomogeneity. We argue that the classical action that leads to the correct ...
