英文摘要	the coulomb explosion of ammonia clusters induced by nanosecond laser at 532 not with an intensity of similar to 10(12) wcm(-2) has been studied by time of flight mass spectrometry. the dominant multiply charged ions are n3+ and n2+ with kinetic energies of 110 and 50 ev respectively. the electrons generated from the multiphoton ionization are heated through inverse bremsstrahlung by the laser field when colliding with neutral or ionic particles. when their energies surpass the corresponding ionization potentials of the molecules or ions, the subsequent electron impact ionization may take place thus resulting in multi-charged nitrogen ions. covariance analysis is made to study the possible pathways of the coulomb explosion.
