  Abstract:

  We study the barrier penetrability in the frame of the Lindblad   theory  of open quantum systems. In addition to the diagonal   elements of the  density matrix, leading to the Gamow’s   formula, new terms, describing  energy dissipation and   spectral line broadening effects are obtained. It  is shown   that the presence of a dissipative environment increase the    barrier penetrability, in accordance with a very simple   physical  interpretation: for a system initially found in   its ground state the  dissipation can lead only to   transitions to the reaction channels where  lower-energy   levels exist.
