This paper studies the coherent acceleration of ions interacting with twoelectrostatic waves in a uniform magnetic field B0. This is a generalization ofan earlier analysis of waves propagating perpendicularly to B0 to include theeffect of wavenumbers along B0. The Lie transformation technique is used todevelop a perturbation theory describing the ion motion, and results arecompared with numerical solutions of the complete equations of motion. Coherentenergization occurs when the Doppler-shifted wave frequencies differ by nearlyan integer multiple of the ion cyclotron frequency. When the difference in theparallel wavenumbers of the two waves is increased the coherent energization ofions is limited to a small part of the phase space. The energization of ionsand its dependence on wave parameters is discussed.Comment: 22 pages, 16 figures. Corrected typo
