Phenomenon of Gamma-Ray Bursts as Relativistic Detonation of Scalar   Fields
  In the modern Universe the existence of various forms of scalar fields is supposed. On the one hand these fields can explain recently discovered positive $\Lambda$-term(see e.g. Ref. \cite{ref:Sahni}), on the other hand its form cluster systems creating gravitational wells for galaxies and their clusters. At that a natural hypothesis is the existence of compact configurations ("stars") from scalar fields with a large enough energy density and total mass. The hypothesis is that the energy of these fields can be converted in relativistic plasma by an explosive way. Such process can be initiated by collision of relativistic particles which form a relativistic microscopic fireball. Thus effective temperature can amount to value sufficient for change of phase for scalar fields. Then the wave of relativistic "detonation" similar to the same process in classical physics will be spread from this source. In this paper the parameters of such field star and process of detonation are estimated. If the effect of the indicated change of phase (or something similar to one) exists, it is possible to get the parameters of relativistic plasma (macroscopic fireball) which could generate gamma - bursts. If in the modern Universe there is such unique form of a matter as fields of high density it would be strange for Nature not to take advantage of the possibility to convert their energy to radiation by an explosive way.
