例句：
1
To make cold antihydrogen, the experimenters must slow down the antiprotons to a temperature similar to that of the positrons.
2
It means that our measurement of the antiproton's mass relative to the electron is now almost as accurate as that of the proton.
3
4
Next the antiatoms encounter a strong electric field that strips apart the antiproton and positron of the weakly bound antiatoms .
5
6
The Tevatron continues to break records for luminosity, the number of high-energy proton-antiproton collisions it produces.
7
Some antiproton annihilations produce a shower of positrons, which in turn produce 511-keV gamma rays, two of which may be detected.
8
The antiprotons are then pushed into the same trap as the positrons and left to mingle for a second or so.
9
10
It has developed better techniques for cooling both positrons and antiprotons, which should allow it to trap more anti-atoms.
11
12
Successive bunches of antiprotons from the Antiproton Decelerator can be added to the trap, a process invented by TRAP called stacking.
13
14
A chain of reactions, starting with a beam of laser-excited cesium atoms, transfers the positrons to the antiprotons to form antihydrogen.
15
Coaxing hot and bothered antiprotons and positrons to couple is quite a task.
16
17
18
Pairs of protons and antiprotons are also directly produced in the cosmic ray collisions with the atmosphere.
19
To trap antiprotons, one would have to reverse the electric field, thus inverting the potential.
20
21
Physicists have long suspected that antiprotons must become trapped in a belt around Earth. Now they've found it.
22
The antineutrons escape the atmosphere and then decay into antiprotons at much higher altitudes.
23
An idea was being floated to use protons and their antimatter equivalents to do just that.
24
25
26
After a collection period, these antiprotons are released and detected by their annihilations on the nearby walls.
27
28
Antiprotons are particles with the same mass as more familiar protons but with opposite charge.
29
30
This constitutes "the most abundant source of antiprotons near the Earth" , say the PAMELA team.
