In the strongly two-dimensional (2D) organic metal - anomalous damping effects of the magneto-quantum oscillations are reported for the special conditions (i.e., to the conducting planes), and . A new observed oscillation frequency is found to control these effects at low Landau level filling factors of F0. This is of special interest since the damping effects are attributed to a localization of electrons which may occur in 2D systems especially at low .
