8 pages, 5 figures.-- PACS nrs.: 34.50 Ez.We report an experimental determination of the k(00-->02) rate coefficient for inelastic H2:H2 collisions in the temperature range from 2 to 110 K based on Raman spectroscopy data in supersonic expansions of para-H2. For this purpose a more accurate method for inverting the master equation of rotational populations is presented. The procedure permits us to reduce the measured k(00-->02) rate coefficient to the corresponding σ(00-->02) cross section in the range of precollisional energy from 360 to 600  cm–1. Numerical calculations of σ(00-->02) carried out in the frame of the coupled channel method are also reported for different intermolecular potentials of H2. A good agreement is found between the experimental cross section and the numerical one derived from Diep and Johnson's potential [J. Chem. Phys. 112, 4465 (2000)].This work was supported by the Spanish Ministerio de Ciencia y Tecnología, Research Project No. BFM2001-2276.Peer reviewe
