The Fermi surface of the organic superconductor {beta}-(ET){sub 2}IBr{sub 2} investigated by measurements of the de Haas - van Alphen (dHvA) effect has been found to have the typical two-dimensional cylindrical form. A small amount of corrugation could be quantitatively determined by the distinctive angular dependence of beating nodes. the existence of up to four almost identical frequencies in the dHvA signal may be explained by magnetic interaction effects within the samples. Due to the 1/cos{Theta}- behavior of the effective mass spin-splitting zeros could be detected.
