Multiple Coulomb scattering of muons in lithium hydride

Regeneration of lithium aluminum hydride.

Lithium aluminum hydride (LiAlH(4)) is a promising compound for hydrogen storage, with a high gravimetric and volumetric hydrogen density and a low decomposition temperature. Similar to other metastable hydrides, LiAlH(4) does not form by direct hydrogenation at reasonable hydrogen pressures; therefore, there is considerable interest in developing new routes to regenerate the material from the ...

Stark deceleration of lithium hydride molecules

We describe the production of cold, slow-moving LiH molecules. The molecules are produced in the ground state using laser ablation and supersonic expansion, and 68% of the population is transferred to the rotationally excited state using narrowband radiation at the rotational frequency of 444 GHz. The molecules are then decelerated from 420 m/s to 53 m/s using a 100 stage Stark decelerator. We ...

Reduction of Halomethanes with Lithium Aluminum Hydride

A study has been made of t he reactions of lithium aluminum hydride with methyl bromide, methylene chloride, meth ylene bromide, methylene iodide, chloroform, bromoform, and carbon t etrachloride. Except for hydrogen and unreacted h alida, essentia lly pure methane was formed in each case. The amount of hydrogen evolved increased with the n umber of halogen atoms in the molecule, reaching a max...

Comments on multiple scattering of high-energy muons in thick layers

We describe two independent methods to calculate the angular distribution of muons after traversing a thick scatterer due to multiple Coulomb scattering. Both methods take into account the nuclear size effect. We demonstrate a necessity to account for the nucleus extension as well as incoherent scattering on atomic electrons to describe the muon scattering at large angles in thick matter layers...
