This article is the ninth part of the scientific project under the general title "Geometrized Vacuum Physics Based on the Algebra of Signature " [1,2,3,4,5,6,7,8]. In this article, based on exact solutions of the Einstein vacuum equation, are proposed metric-dynamic models of the electron and positron "neutrino" in the initial state, i.e. at the moment when it breaks away from the core of the corresponding "particle", and in the final state, when almost all the rotational energy of the initial "neutrino" is converted into its accelerated translational motion. It is shown that Riemann-ian geometry allows for the consideration of "neutrinos" of various scales: molecular "neutrinos", cluster "neutrinos", planetary "neutrinos", galactic "neutrinos", etc. The article proposes methods for generating "neutrinos" of various scales, convenient for conducting inexpensive experiments to clarify their properties. Of particular interest are "neutrinos" in the final state, since the metric-dynamic model of such a "neutrino" does not contain restrictions on the speed of its translational motion. That is, a "neutrino" in the final state does not have inertia, and theoretically can move at a speed significantly exceeding the speed of light. The article proposes a method for registering super-luminal "neutrinos" in the final state.
