Exotic Localized Coherent Structures of New (2+1)-Dimensional Soliton Equation

The variable separation approach is used to obtain localized coherent structures of the new (2 1)-dimensional nonlinear partialdifferential equation. Applying the Backlund transformation and introducing the arbitraryfunctions of the seed solutions, the abundance of the localized structures of this model are derived. Some special types ofsolutions solitoff, dromions, dromion lattice, breathers and instantons are discussed by selecting the arbitrary functionsappropriately. The breathers may breath in their amplititudes, shapes, distances among the peaks and even the numberof the peaks.

Resonances in the dtµ molecular ion between tµ(n=2) and dµ(n=2) thresholds

Elastic and inelastic cross sections in collisions of a tµ atom in 2s and 2p states on deuteron have been obtained within the framework of a four-channel adiabatic approximation for the case of total orbital angular momentumJ=0. The calculated data has been applied to verify the existence of resonance in the dtµ molecular ion at 0.8 eV above the tµ(n=2) threshold. It appears that the second and third resonant states (at 0.8 eV and at 7 eV above the tµ threshold) in a series converging to the dµ(n=2) threshold do not produce any resonant structure in the energy spectrum. The higher vibrational states are visible in the spectrum, however their widths are about 0.1 eV and therefore their life-times are about 10^–15 s which allows to conclude that these states could not play an important role in the µCF cycle as well as in processes of diffusion of muonic atoms.
