We calculate the quasiclassical probability to emerge the quantum fluctuation which gives rise to the quark-matter drop with interface propagating as the self-similar spherical detonation wave (DN) in the ambient nuclear matter. For this purpose, we make use of instanton method which is known in the quantum field theory.

Detonation Temperature

Using elements of the theory of classical detonation and previously obtained relations for spherical waves, the author tried to establish the range of admissible values of temperature, Mach numbers, and specific hydrogen content in the gas mixture of the possible existence of normal spherical detonation. The work took into account the critical values of the parameters associated with the kinetics of the chemical reaction at the front of the blast wave and the parameters that determine the intensity of the shock transition (minimum and maximum Mach number) for a given reacting medium. Using the example of the interaction of hydrogen and oxygen in a hydrogen-oxygen mixture, it was possible to graphically determine the range of values of the main physical quantities and parameters - the critical temperature, the detonation temperature of the quiescent medium, and the specific hydrogen content in the mixture required for spherical detonation. Mathematical modeling of the process was carried out at a fixed value of the pressure of the gaseous medium.

Limiting Values

Minor fluctuations of velocity are frequently observed in gaseous mixtures whose compositions lie near to the limiting values of sustained propagation of detonation. Various possible origins of these fluctuations are discussed. In cylindrical tubes, they commonly take the form of a spinning detonation front. In order to study these effects in detail, previously described methods for making accurate observations near the limits have been extended in various ways. Use of multiple probes set radially in a standard detonation assembly permitted determination of the profiles of spinning ionization fronts to the detonation wave. In some cases, the existence of multiple spin heads detected by these means could be confirmed by soot-trace techniques. For any given mixture, fluctuations in the form of spinning ionization fronts are often remarkably reproducible in a particular tube.
