Fluxes of quasicaptured protons at L approx 3.2 during geomagnetic disturbances were observed. It is assumed that the quasicaptured protons result from the interaction of captured protons with hydromagnetic waves. It is found that the Fermi mechanism of interaction of waves and particles influence the dynamics of captured protons in the vicinity of the plasmopause where there is a well expressed trough in the distribution of the cold plasma. These conditions occurred during magnetic disturbances. It is stated that a full experiment to check the effectiveness of this scattering mechanism must include measurements of the flux and spectrum of protons plus measurements of cold plasma density and the amplitude of Alfven waves with a period of 3 to 10 seconds.
