antihydrogen

Examples

• All

• The convertible energy of 50,000 antihydrogen atoms is, according to Einstein's famous equation, about 1.5 x 10^-5 Joules.

• The other option, which the ATRAP group has chosen, is to perform the measurements on antihydrogen held in a trap.

• The experiment is so hard that forming antihydrogen is a big deal.

  Academic text (2002)

• Occasionally, one of the newly produced positrons (e+) moved in the same direction and with the same speed as the "mother" p, which then picked it up to form antihydrogen.

  Academic text (2002)

• Hangst commented that neutral traps for antihydrogen are not very deep and thus require the atoms to be as cold as a few degrees Kelvin.

  Academic text (2002)

• He and his ATRAP collaborators are also attempting to produce and detect antihydrogen.

  Academic text (2002)

• ATHENA, a second antihydrogen collaboration at CERN, has now accomplished that feat, detecting more than 100 atoms.

  Academic text (2002)

• In 1999, the ATRAP team confined antiprotons and positrons in the same trap (n3) at temperatures as low as 4 K, but has not yet shown that antihydrogen is formed.

  Academic text (2002)

• CERN's Antiproton Decelerator (AD) facility, created largely to support antihydrogen research (see PHYSICS TODAY, October 2000, page 22), supplies antiprotons traveling at about one-tenth the speed of light.

• Researchers at CERN successfully created the first stable sample of antihydrogen in the lab.
