Quantum scattering problem without partial-wave analysis
  We have suggested a method for treating different quantum few-body dynamics without usual partial-wave analysis. With this approach new results were obtained in the physics of ultracold atom-atom collisions and ionization and excitation/deexitation of helium ions. The developed computational scheme opens new possibilities for analysis the actual problem of ultracold atom wave-packets collisions in strong laser or magnetic confinement.
