我们提出了一种新的机制，用于产生高能量（E>3 keV）的氘，适合于诱导dd核聚变，基于多电子电离和库仑爆炸的含氘分子团簇，例如，（D_2O）_n，在强（10（16）-2 × 10（18）W/cm ~ 2）激光场中。结合分子动力学模拟，揭示了（D_2 O）_n杂原子团簇库仑爆炸比（D）_n团簇具有的重要优势.这涉及到D+动能的显著增加和氘核的窄的高能分布。
We propose a new mechanism for the production of high-energy ( E>3 keV) deuterons, suitable to induce dd nuclear fusion, based on multielectron ionization and Coulomb explosion of heteronuclear deuterium containing molecular clusters, e.g., (D2O)n, in intense ( 10(16)-2x10(18) W/cm2) laser fields. Cluster size equations for E, in conjunction with molecular dynamics simulations, reveal important advantages of Coulomb explosion of (D2O)n heteronuclear clusters, as compared with (D)n clusters. These involve the considerably increased D+ kinetic energy and a narrow, high-energy distribution of deuterons.
