本文在PdDx晶格动力学中对4D和8D团簇与Pd 4D壳层电子的暂态玻色型凝聚机制进行了深入的模拟。对于四面体和八面体对称凝聚，建立了四面体和八面体对称凝聚的四重态e~*(4，4)电子准粒子和八元耦合e~*(8，8)与D团簇形成超屏蔽d-d和d-团簇库仑势垒的模型，并进行了讨论。基于电子准粒子展开理论(EQPET)，对四面体和八面体对称凝聚的模式聚变率进行了估算，这些聚变率由2D、3D、4D和8D聚变率以及每个模式的特征值组成。基于给定的模式聚变率，我们可以通过知道D团簇密度的时间平均值来估计宏观聚变率(f/S/cc)。在4He主灰和各种次级蜕变反应的作用下，4D和8D的聚变率可达到几到几百W/cc，2D聚变的中子产生率将比4He产生的中子产生率小10-12个数量级。因此，在凝聚态物质中的氦团聚变中，几乎看不到中子。
The present paper makes deepened modeling for the mechanism of transient Bose-type condensation for 4D and 8D clusters with electrons from Pd 4d-shell in PdDx lattice dynamics. Formation of quadruplet e*(4,4) electronic quasi-particle and octal-coupling e*(8,8) around lattice focal points with D-clusters which realize super screening for d-d and d-cluster Coulomb barrier is modeled for tetrahedral and octahedral symmetric condensations and discussed. Based on the electronic quasiparticle expansion theory (EQPET), modal fusion rates which are composed of 2D, 3D, 4D and 8D fusion rates with characteristic values for each mode are estimated for the tetrahedral and octahedral symmetric condensations. Based on given modal fusion rates we can estimate macroscopic cluster fusion rates (f/s/cc) by knowing time-averaged values of D-cluster densities. Several to few hundreds w/cc level fusion rates for 4D and 8D can be foreseen with major ash of 4 He and a variety of secondary transmutation reactions, and neutron production rate by 2D fusion will be with 10-12 orders smaller magnitude than that of 4 He production. Neutrons are therefore hardly visible in deuteron cluster fusion in condensed matter.
