Description of narrow resonances using two-potential formula
 Bednařík, Lukáš ; Čížek, Martin (advisor) ; Houfek, Karel (referee)
In the presented thesis we study tunneling problems with projection formalism and two potential approach. We apply this approximative method proposed by S.A. Gurvitz in [4] to two new potentials with a quasistationary state. In the next chapter we generalize this method to one-dimensional nonsymmetric potential. A new formula is found and used for calculation of energy width. We compare our results with a numerical method of complex scaling. Finally, we discuss three-dimensional potential. One axis of symmetry is assumed and we derive relatively simple formula for energy width.
