| Zusammenfassung |
| We study stable axially and spherically symmetric spatial solitons in plasma
with diatomic ions. The stability of a soliton against collapse is
provided by the interaction of induced electric dipole moments of ions with
the rapidly oscillating electric field of a plasmoid. We derive the new
cubic-quintic nonlinear Schrödinger equation, which governs the soliton
dynamics and numerically solve it. Then we discuss the possibility of
implementation of such plasmoids in realistic atmospheric plasma. In
particular, we suggest that spherically symmetric Langmuir solitons,
described in the present work, can be excited at the formation stage of
long-lived atmospheric plasma structures. The implication of our model for
the interpretation of the results of experiments for the plasmoids generation
is discussed. |
