The search for muon catalyzed d³He fusion

The theoretically and experementally discovered formation of d³Heµd-molecules is able to search for muon catalyzed d³He- fusion reaction similar of the d-µ-t fusions:

dµ+³He-->d³Heµ-->⁴ He(3.66Mev)+p(14.64Mev)+µ

The experimental limit on the d³He-µ-d fusion rate λ_f≤ 4∙10⁸s^-1 was firstly set in Gatchina experiment.
Also, the measurement of the muon transfer rate ( λ_dHe = 1.24(5) ∙ 10⁸ s^-1) from deuterium to ³He at room temperature was performed.

This result confirmed the teoretically predictions about a mesomolecular mechanism of the process muon transition.

The search d³He-fusion was continued on intense muon beem at PSI in 1996 – 1997.

λ_f ≤ 6 ∙ 10⁴ s^-1 wich is more than three orders of magnitude lower than the previously existed limit.

Also, in this experiment was performed the measurements of the muon transfer rates at low temperatures:

λ_dHe(39.5 К) = 2.33(16) ∙ 10⁸ s^-1     λ_dHe(50 К)= 2.32(9) ∙ 10⁸ s^-1.

These results are in good agreement with theoretical predictions.
