We present a novel model for collisional energy transfer between ions and neutral molecules in the quadrupole radio-frequency trap. Calculated results quantitatively reproduce the dependence of the ion temperature T_i on the buffer gas pressure P_n, observed on Mg⁺ ions and several collision partners(H₂, He, and CH₄). It is deduced from the present model that T_i is proportional to P_n^-1/3 in the low-pressure range below 10^-6, Torr, in good agreement with the experimental results.
