For this Master thesis, multiphoton ionisation processes of Lithium-6 atoms from an optical dipole trap have been investigated and the momentum distributions of the resulting ions over the whole solid angle in a Reaction Microscope have been obtained for the first time. The atoms have first been trapped in a magneto-optical trap, before being transferred into the purely optical dipole trap. Measurements for five different peak intensities in the range of 6:5 x 10¹³ W=cm² to 6:5 x 10¹⁴ W=cm² have been carried out, where a femtosecond laser has been used as the projectile beam. The experimentally obtained momentum distributions are consistent with formerly executed comparable experiments and offer a basis for future experiments.
