SEARCH FOR ANTIHYDROGEN AT LEAR

The antihydrogen atom (<(H)over bar(0)>) = (p) over bar e(+)), the sim plest atomic bound state of antimatter, has not yet been observed. The production of this object is an experimental challenge, and further, it is suited for investigations of fundamental properties. <(H)over ba r(0)>) is suggested to be produced in (p) over bar Z collisions. The e xperiment described has been a first ''ad hoc'' attempt to measure a p ossible (H) over bar(0)>) production parasitically to an internal clus ter-target experiment at LEAR/CERN, but has now developed to the exper iment PS210.
