Production of 100 Sn in fusion reactions via cluster emission channels
The possibilities of production of the doubly magic nucleus 100 Sn in complete fusion and quasifission reactions with stable and radioactive ion beams are investigated within a dinuclear system model. The excitation functions for production of the exotic nuclei 100−103 Sn via cluster emission channels are predicted for future experiments.
Emission of charged particles from excited compound nuclei
The process of complex fragment emission is studied within the dinuclear system model. Cross sections of complex fragment emission are calculated and compared with experimental data for the reactions 3 He + nat Ag, 78,86 Kr + 12 C, and 63 Cu + 12 C. The mass distributions of the products of these reactions, isotopic distributions for the 3 He + nat Ag and 78 Kr + 12 C reactions, and average total kinetic energies of the products of the 78 Kr + 12 C reaction are predicted.
Mathematical Time and Physical Time in the Theory Of Relativity
In the Theory of Relativity time is an imaginary quantity that can not be observed; it is a multiplication of a number that indicates duration of material change and number i that is an imaginary number. i on the square is -1. Time i⁄t is a mathematical time that describes the speed and the duration of material change. In the Universe one can observe physical time only as a stream of material change. It is not that change run in physical time, change itself is physical time.. Distinction between imaginary mathematical time and visible physical time opens some new perspectives into interpretation of Theory of Relativity. c
