The stability of a tokamak plasma to ideal and resistive internal kink modes in the presence of an energetic trapped-particle population is analyzed. Domains of stability are found for both slowing-down and Maxwellian particle distributions. The stable domains are at moderately high plasma beta and involve a significant, but easily obtainable high-energy trapped-particle density.
