That laser technique won't work for antiprotons because anti-hydrogen is difficult to produce and harness.
The project previously scored a pioneering breakthrough by trapping 38 atoms of anti-hydrogen for more than 16 minutes - a significant improvement on past efforts.
At least 38 anti-hydrogen atoms were produced and trapped for approximately one tenth of a second, giving researchers a long enough window of opportunity to study them.
Scientist Jeffrey Hangst, the spokesman for the team, said they had managed to trap 38 anti-hydrogen atoms individually.
The anti-hydrogen bonds have thus been designated blue-shifting hydrogen bonds.
For example, the known synthesized elements (their hyperbolas are more exact): anti-hydrogen, antideuterium, and anti-helium occupy symmetric places in both quadrants.
The cost-efficient anti-hydrogen sulfide system removes the substance from gas streams using a special absorbent, it said.
A bit more recently, announcements of the Bose-Einstein condensate and the possible creation of an anti-hydrogen atom have pushed the limits of matter.
Further study is motivated not only by fundamental interest but also because experiments may shed light on the physics of dense cores of gas giant planets like Jupiter, or guide efforts to create anti-hydrogen through the recombination of positrons and anti-protons.
In an astonishing breakthrough this summer, the four, along with a team of international physicists at the nuclear research laboratory Cern in Geneva, were able to trap 38 atoms of anti-hydrogen for over 16 minutes.
