µCF experiments
During 1994-1996, a series of µCF experiments were performed
at
PSI - PNPI
- IMEP - LBNL - TUM collaboration.
These experiments aimed at high precision studies of the d-µ-d fusion in D2 and HD gases in a wide temperature range 28 - 350K.
The Gatchina ionization time projection chamber has been used to detect the dd-fusion reaction producs
The main parameters of the d-µ-d fusion have been measured with high absolute precision ~1%:
- ddµ molecule formation rates
- branching ratios of the dd-fusion channels dd->(He3+n ; t+p),
- muon sticking probability,
- directand backdecay spin-slip raties in thedµ-atom.
The resulting data were analyzed used µ;CF theory
that allowed to check several most important theoretical parameters
In particular,the energy ε11 of the losely bound level
in the ddµ- molecule
was determined with unprecedent absolute accuracy of ± 0.3meV.
