摘要: The interaction of C2H5X, 1-C3H7X, 1-C4H9X, where X = I, Br, Cl, with strong (1 × 1013−1.2 1014 W/cm2) 35 ps laser pulses at 1064 nm is studied by means time-of-flight mass spectrometry. multielectron ionization following the C−X bond elongation has been verified for molecules. By combination intensity dependence ion yields, estimated kinetic energies released fragment ions, and their angular distributions, we have identified different dissociation channels transient multiply charged parent ions. From on ratio doubly halogen ions to singly ones, it concluded that molecular coupling field increases size.
