Muon Catalyzed Fusion with Intense Muon Beam

在加拿大温哥华TRIUMF的日加合作超导Muon通道上，利用强负Muon源进行了新型的Muon催化聚变(MUF)相关实验。在1990-1992年期间，在以下两个实验项目中取得了显著的成果：1)从DMU到HeH的Muon转移反应。通过测量这个转移反应所涉及的X射线，发现该反应主要是通过(DMU)基态形成的(Dhemu)分子进行的。此外，根据~3He和~4He之间显著的同位素依赖关系的发现，清楚地发现了(Dheme)分子的(Hemu)粒子发射的证据。2)通过muCFs产生慢的mU-，可以认为muCF是10keV慢mU的来源。对于这种缓慢的微米级生产，通过对3 MeV质子的探测，证实了在1 mm厚的H_2层上涂覆一层(几微米)D_2层中实现了(Ddu)-MuCF。在H_2(D_2)层产生2 eV(DMU)的作用下，产生了这种MuCF现象。与这些实验结果相关的是，理论研究取得了进展。通过复坐标旋转法和反转过程的截面计算，预测了(Dhemu)分子粒子衰变的可能性。同时发现，(Dhemu)分子的有限大小对于[(Dtu)d，2e]的准分子水平很重要，这决定了(Dtmu)分子共振形成反应的匹配条件。

New types of muon catalyzed fusion (mucf) related experiments have been carried out by using intense negative muon source at the Japan-Canada cooperative superconducting muon channel of TRIUMF in Vancouver, Canada. In the period of 1990-1992, significant output has been obtained in the following two experimental projects.1)Muon transfer reaction from (dmu) to HeBy measuring X-rays involved in this transfer reaction, it was found that the reaction mainly proceeds via (dHemu) molecule formed from the ground state of (dmu). Also, based on the discovery of a marked isotope dependence between ^3He and ^4He, an evidence of (Hemu) particle emission dsecay of the (dHeme) molecule was clearly found.2)Slow mu^- production via muCFThe muCF can be considered as a source of 10 KeV slow mu^-. Towards this slow mu^- production, the realization of (ddmu)-muCF in a thin (a few mum) D_2 layer coated on 1mm layer of H_2 with 1,000ppm D_2 was confirmed by detecting 3MeV protons. This muCF phenomena occured with the help of 2eV(dmu) production from H_2(D_2) layer.Related to these experimental achievements, progress was made in the theoretical studies.The possibility of the particle decay of (dHemu) molecule was predicted both by complex coordinata rotation method as well as by the cross section calculation of the invergs process.Also, importance of the finite size of the (dHemu) molecule was found for the level of the pseudo-molecule of [(dtmu)d, 2e] which determined the matching condition in the resonant formation reaction of the (dtmu) molecule.
