Outline of Final Research Achievements

We have successfully developed a high quality energy-tunable positronium beam by the photodetachment of accelerated positronium negative ions. This ions were produced efficiently using sodium coated tungsten surfaces. We have started applications of this beam. We have observed a shape resonance of positronium negative ions by scanning laser wave length. Specular reflection of positronium from solid surfaces and the dependence on the polarization of laser light have also been studied. We have studied the formation of neutral positronium atoms and positronium negative ions at surfaces and ion desorption from surfaces induced by positron annihilation.
