Holt, R J

This patent describes a polarized internal target apparatus. The apparatus consists of structural means having diametrically opposite openings for the passage of a particle beam and otherwise defining a cell region, means for forming a mixture of target gas and alkali gas atoms at a ratio of the order of about 20-200:1 and introducing the mixture to the cell region. The apparatus also has a means for passing a high intensity polarized light source into the mixture to polarize the alkali atoms, the polarized alkali metal gas atoms in collisions with the target gas atoms causing polarization of the target gas atoms, and means for subjecting the target cell to a magnetic field of the order of 3-50 gauss. The target gas atoms are hydrogen or deuterium and the alkali atoms being sodium or potassium.
