H_3^{++}$ molecular ion in a strong magnetic field: triangular configuration
The existence of the molecular ion in a magnetic field in a
triangular configuration is revised. Variational method with an optimization of
the form of the vector potential (gauge fixing) is used. It is shown that in
the range of magnetic fields the system , with
protons forming an equilateral triangle perpendicular to magnetic line, has a
well-pronounced minimum in the total energy. This configuration is unstable
towards decays and . Triangular configuration of
complements in the linear configuration which exists for

A hydrogenic molecular atmosphere of a neutron star
A model of a hydrogenic content of atmosphere of the isolated neutron star
1E1207.4-5209 is proposed. It is based on the assumption that the main
component in the atmosphere is the exotic molecular ion and that
there exists a magnetic field in the range of G.
Photoionization H_3^{2+} \rar e + 3p and photodissociation H_3^{2+} \rar H +
2p correspond to two absorption features at 0.7 KeV and 1.4 KeV, respectively,
discovered by {\it Chandra} observatory (Sanwal et al, 2002). The model
predicts one more absorption feature at 80-150 eV corresponding to
photodissociation H_3^{2+} \rar H_2^+ + p.Comment: 8 pages, 1 figur
