【 摘 要 】

Charge transfer and formation of the collision complexes have been studied experimentally in fragmentation of the furan molecules in collisions with He+cations. The excited atomic and diatomic fragments of furan have been identified using collision-induced luminescence spectroscopy. Charge transfer ionization of the furan molecules has been observed in production of helium atoms in the excited 1s4d1D2,3D1,2,3states. The fragmentation yields of the excited fragments have been measured as a function of the projectile energies (velocities) in the range 5-1000 eV. Enhancement of the fragmentation yields occurring at lower velocities may indicate formation of the [He-C4H4O]+collision complexes prior to dissociation.
