The muonic molecular ions having He as a nucleus do not form bound states. However, their resonant states play a role in muon catalyzed fusion. They are considered scavengers of muons. At very high densities these resonances may enhance the stripping of muons from muonic He when its kinetic energy has been slowed down after (dt ) or (dd ) fusion. Quantitative investigation has been slowed down because very little is known about these resonances. A variational method, developed for the accurate determination of the (dt ) bound state properties, is well suited for studying these resonances. Excellent resonance energies and widths have already been computed for a number of resonant states of (dt )+ below the n=2 threshold of (d ) and (t ). Preliminary calculations indicate the existence of similar resonances in (.d )++ and (3Hed )++. The proposed research will provide accurate positions, widths and other properties of all these resonances.

以He为核的μ子分子离子不形成束缚态。然而，它们的共振态在μ子催化聚变中发挥作用。它们被认为是μ介子的清除者。在非常高的密度下，当 (dt ) 或 (dd ) 聚变后其动能减慢时，这些共振可能会增强 μ 子从 μ He 中的剥离。由于对这些共振知之甚少，定量研究已经放缓。为准确测定 (dt ) 束缚态特性而开发的变分方法非常适合研究这些共振。对于低于 (d ) 和 (t ) 的 n=2 阈值的 (dt )+ 的许多谐振态，已经计算出出色的谐振能量和宽度。初步计算表明 (.d )++ 和 (3Hed )++ 中存在类似的共振。拟议的研究将提供所有这些共振的准确位置、宽度和其他属性。
