REACTION DYNAMICS OF THE CA(D-1(2), P-3(J))-]CAI-ASTERISK+R (R=CH3, C2H5 AND N-C3H7) SYSTEM - CHEMILUMINESCENCE, PHOTON YIELD, ELECTRONIC BRANCHING RATIO AND INFLUENCE OF THE RADICAL GROUP(RI)

The Ca(D-1(2), (3)p(1)) + RI (R = CH3, C2H5, n-C3H7) --> CaI(A,B) + R reaction system has been studied by measuring its chemiluminescence un der beam gas conditions, Absolute values of the reaction cross-section s were determined at low collision energy (E) over bar(T) less than or equal to 0.20 eV, In addition, the electronic branching ratio, photon yield and influence of the radical size group on the reaction cross-s ection have been estimated, The results are discussed in the light of different reaction mechanisms involving the attacking Ca atom into the C-I bond.
