Resonant mesomolecule formation
The dtm and ddm resonant fusion rates are calculated taking into account
finite resonance width and subthreshold resonances. Calculations do not use
multipole expansion of the potential. The obtained ddm resonant fusion rates
are compared with recent data at 30-360 K.Comment: 3 pages, 2 figure

The Gauss Map of Hypersurfaces in 2-Step Nilpotent Lie Groups
In this paper we consider smooth oriented hypersurfaces in 2-step nilpotent
Lie groups with a left invariant metric and derive an expression for the
Laplacian of the Gauss map for such hypersurfaces in the general case and in
some particular cases. In the case of CMC-hypersurface in the
(2m+1)-dimensional Heisenberg group we also derive necessary and sufficient
conditions for the Gauss map to be harmonic and prove that for m=1 all
CMC-surfaces with the harmonic Gauss map are "cylinders"
On a number of rational points on a convex curve
Let be a bounded convex curve on a plane. Then . It streghtens the classical result of Jarn\'\i k (an
upper estimate ) and disproves a conjecture of Vershik on existence
of the so-called {\it universal Jarn\'\i k curve}.Comment: 8 pages, submitted to FA
On the phase of the off-shell scattering amplitudes
We prove that the phase of the partial wave amplitude does not depend on the
off-shell 4-momentum squared of one of the scattered particles.Comment: 2 pages, latex fil
Nucleon Spin Puzzle: Ten Years Later
This is a brief survey of the present state of ideas concerning the parton
content of the nucleon spin after their ten-years evolution since the discovery
of the EMC.Comment: 5 pages, latex fil
Random membrane model for lattice gluodynamics
odel for studying coupling dependence on lattice spacing a in gluodynamics is
suggested. The model predicts $g-> g_{0}>0 with a->0. Free energy density in
the model does not depend on temperature
Spatial string tension in gluodynamics at finite temperature in a spherical model approximation
Spatial string tension is computed in finite temperature gluodynamics on
asymmetric lattices in a spherical model approximation. Conditions of scaling
behavior are specified. Discrepancies with a standard renormalisation procedure
are discussed.Comment: 13 pages, revte
