中文摘要	this paper reports that coulomb explosions taken place in the experiment of heteronuclear deuterated methane clusters ((cd4)(n)) in a gas jet subjected to intense femtosecond laser pulses (170 mj, 70 fs) have led to table-top laser driven dd nuclear fusion. the clusters produced in supersonic expansion had an average energies of deuterons produced in the laser-cluster interaction were 60 and 1.5 kev, respectively. from dd collisons of energetic deuterons, a yield of 2.5(+/-0.4)x10(4) fusion neutrons of 2.45 mev per shot was realized, giving rise to a neutron production efficiency of about 1.5 x 10(5) per joule of incident laser pulse energy. theoretical calculations were performed and a fairly good agreement of the calculated neutron yield with that obtained from the present experiment was found.
