We have observed resonant-energy-transfer collisions between K Rydberg atoms. We have tuned the [ital ns][sub 1/2]+([ital n][minus]2)[ital d][sub [ital j]][r arrow][ital np][sub [ital j][prime]]+([ital n][minus]1)[ital p][sub [ital j][prime][prime]] collisional process into resonance with a static electric field. The measured resonance field positions from [ital n]=24 to 29 agree well with the calculated positions. We show that the dipole-dipole selection rule, [Delta][ital m][sub [ital j]]=0,[plus minus]1, is valid for these resonances but that [Delta][ital J]=0,[plus minus]1 is not, due to the presence of the electric field. In addition, the polarization of the lasers used to excite the Rydberg states can suppress many of the resonances.
