β¦ Synopsis
The jackknife test of Rothstein et al. is applied to discrimination between severaI different models used to compute the rotationally inelastic cross sections for the Ar-N2 system. The modified exponential models are the best models, except for the case where the energy gap is small, when power laws are best.

The p-helicity&wupling (PHD) scheme is applied to high rotational transitions in the AI f Nz system and found to give more accurate cross sections and opacity functions than other known approximations. \* hp the phelicity is defined as the projection of J on the direction of p -the linear momentum.
Rotational energy transfer cross sections are determined for NO(A 'Z +, u' = 0, N' = 0, 7, and 15) + He and NO(A 'E +, u' = 0, N' =O) +Ar by the two-color, double-resonance ionization method. Rotational jumps up to W = 8 take place as a single collision event. The cross sections determined are discu
