• Energetic trapped particles bounce resonance excitation of magnetohydrodynamic(MHD) ballooning mode is studied by using the averaged ballooning mode equationin a tokamak with the circular cross section. The bounce resonance contribution oftrapped energetic particles is found to play an important role in the outer inertialregion of the ballooning mode perturbation, and destabilizes the ballooning modewhen the shear effect is not strong. The inhomogeniety of a model slowing downenergetic particle distribution in velocity space, 8F/ 8E< 0, is effective to stabilize thebounce resonant mode.[energettclballooning l{ modeb) ){ slowingltrapped particles, bounce resonance excitation, averagedequatuon, tokamak, circular crosssection, inertial range, stabilizationdown distribution
