Motion of two gravitating spherical stellar shells around a massive central body is considered. Each shell consists of point particles with the same specific angular momenta and energies. In the case when one can neglect the influence of gravitation of one (“light”) shell onto another (“heavy”) shell (“restricted problem”) the structure of the phase space is described. The scaling laws for the measure of the domain of chaotic motion and for the minimal energy of the light shell sufficient for its escape to infinity are obtained.

    In my talk I shall consider the mechanism of self-expansion of a system of N D0-branes into highdimensional non-commutative world-volume investigated by Harmark and Savvidy in [ 1 ]. Here D2brane is formed due to the internal angular momentum of D0-brane system. The idea is that attractive force...

    Possibilities to study the a00-f0 mixing amplitude in meson production reactions in nucleon-nucleon collisions are discussed. It is argued that, even without knowing the production operator, it is possible to gain valuable insights from these reactions.

    We theoretically analyze the angular momentum distribution of molecules desorbing from a surface. The adsorbate is shown to possess the complete point symmetry of the surface if the molecules adsorb in statistically equilibrated local order. Considering the symmetry of the angular momentum...
