✦ Synopsis
The first measurement of the glory structure of the total integral cross section for the scattering of N2 against N2 is reported for the collision velocity range 500-3000 m s -l. A comparison is made between the measured structure and calculations carried out within the infinite-order sudden dynamical approximation using a previously proposed N2-N2 interaction potential [J. Chem. Phys. 84 (1986) 1629]. Reasonable agreement is found between the measured and calculated glory structure. There are, however, small but meaningful differences between the two results, indicating that the negative area of the interaction potential should be increased slightly.
