英文摘要	we have made experimental studies on the generation of deuterium-deuterium fusion neutrons from intense coulomb explosions (ce) of large-size (cd4)(n) cluster jets under the irradiation of intense femtosecond laser pulses. by optimizing the propagation of a laser pulse in the cluster gas and the time delay between the laser pulse and the gas flow, the maximum neutron yield of 2.5 x 10(5), which corresponds to a conversion efficiency of 2.1 x 10(6) fusion neutrons per joule of incident laser energy, has been obtained with a 120-mj, 60-fs laser pulse and cluster jets with an average molecular density of 3.6 x 10(18) cm(-3) and cluster radius of 7 nm. we have demonstrated that the neutron yields can be dramatically increased by using heteronuclear (cd4)(n) clusters as compared with the similar sized homonuclear (d-2)(n) clusters. this enhancement is attributed to the significant increase in the deuteron kinetic energies due to energetic boosting and overrun effects during ce of heteronuclear clusters.
