AB  - Molecular photodissociation is an innovative method for the preparation of polarized atoms andmolecules. It is a fundamental chemical process that involves the absorption of one or morepolarized photons by a molecule including its fragmentation into polarized atomic (or molecular)fragments. Recently, T. P. Rakitzis’ group produced high densities of spin-polarized hydrogenatoms applying molecular photodissociation to hydrogen halides. The obtained densities (10^19cm^−3) and short production times (ns timescales) surpass by several orders of magnitude conven-tional methods such as spin-exchange optical pumping and Stern-Gerlach spin separation. Thesedensity and time regimes make it an ideal candidate for a broad range of applications, e.g., laser-induced acceleration from polarized gas targets and polarized five-nucleon fusion reactions (d-3H,d-3He). The second has been shown to have an increased cross section by ∼50% compared to theunpolarized case. The photodissociation method has been adopted by M. Büscher’s group for theproduction of polarized proton and deuteron beams at the Forschungszentrum Jülich. Here, wereport on the production and detection scheme of these beams.
