| Popis: | p3 over the energy range 0.001 to 20 eV using the electron cooler at the storage ring CRYRING. The H 1 3 are stored and cooled at an energy of 6.5 MeVyamu. The recombined products pass through a “translucent” perforated barrier and their total energy is recorded. Thus all particles are detected. Particles passing through holes (70 mm) deposited 6.5 MeV each in the detector, while those passing through the solid (stainless steel 50 mm thick) are not stopped but give pulses of only 4.7 MeV per atom. Analysis of the pulse height spectrum gives the branching fractions directly. PACS numbers: 34.80.Gs, 34.80.Kw The simplest of polyatomic molecules must surely be the two electron H 1 3 ion. Acting as a proton donor, it is an important intermediate in the formation of many interstellar molecules and it has been shown to be present in the ionospheres of Jupiter [1], Saturn [2], and Uranus [3]. Its principal mode of formation is via the homogeneous reaction [4] H 1 2 1 H2 ! H 1 3 1 H 1 1.7 eV . (1) |
