Kinetic analysis on the ballooning mode in tokamaks has indicated the existence of a residual ballooning mode in the negative shear region ({ital s}{lt}0). The instability has a small threshold in {alpha} (the ballooning parameter), requires a finite ion temperature gradient ({eta}{sub {ital i}}), and is characterized by a broad eigenfunction {phi}({theta}) extending to {theta}{approx_equal}50 in the ballooning space. {copyright} {ital 1996 The American Physical Society.}
