Effective decay rate probability density functions. Power-like dependence may be observed for higher decay rates (a) in log-log scale. The distribution broaden significantly with the increase of r H. Shift of the distribution is visible (b) together with average decay time drop and E U rise for higher r H (inset). The normalization in (b) was carried out in a manner exposing distributions broadening while in (a) the function Φ(k) is properly normalized probability density function.
