Scientist of the University of Ghent discovers natural atom antihydrogen

On February 15, 2005 of the Physics/Einstein Year, the complete story of the discovery of natural atom antihydrogen, started in 1985, was published on-line.
The antihydrogen problem has become a highly mediatic issue, both in the specialized physics and the more general press [1]. A real hype started at the end of 2002 when rivalling CERN-based groups ATHENA and ATRAP both claimed the production of large quantities of artificial antihydrogen. Scientists, wondering about a signature for the presence of this mysterious species antihydrogen, were disappointed as no direct signature whatever was presented. In fact, a spectral identification of antihydrogen is impossible since measuring its spectrum is exactly the goal of ATHENA and ATRAP collaborations.
