Abstract
Ultracold ionizing collisions of laser-cooled Kr isotopes in the 1s(5) [4p(5)5s:P-3(2)] metastable state are investigated. When the collision energy is reduced below the p-wave centrifugal barrier of 80 mu K, th e ratio of the ionizing collision rate between polarized and unpolariz ed Kr-83 atoms is found to decrease. This is a direct evidence of the quantum interference of two identical Fermi particles. The experimenta l results are compared with the calculation based on the simplified in elastic collision theory.
