Abstract
The annihilation frequency of the reaction (Formula presented) at rest in liquid hydrogen has been measured by the Obelix experiment by using different apparatus configurations and trigger conditions. The value obtained is (Formula presented) (Formula presented) With the same data samples, the (Formula presented) annihilation frequency has been determined to be (Formula presented) (Formula presented) The results are discussed within the frame of the present experimental situation. © 2001 The American Physical Society.File in questo prodotto:
