Xinhua news agency, Tokyo, November, 25 (reporter Hua Yi) the latest observations of Japanese
researchers found that lightning does generate positron emission, which comes from the
atmospheric reaction caused by lightning.

The positron is the antiparticle of the electron, is a kind of anti matter, it can not exist, and will
encounter electrons annihilate. Earlier studies have suggested that the release of gamma rays,
when lightning occurs, the high energy rays can touch the light nuclear reactions in the
atmosphere to produce neutrons and positrons. The latest observation of Japan the result
confirms this view.

A team of researchers from University of Tokyo, Kyoto University and other institutions began to
observe gamma rays released from lightning in 2006 and other places along the coast of the
Japan Sea.

At the beginning of February this year, the research team in the 4 Niigata County coastal radiation
detector set in lightning occurs to capture neutron and positron signal. To analyze the signal data,
the researchers found that a nuclear reaction occurs in complex nitrogen atoms of gamma ray
photons and atmospheric lightning triggered in this light nuclear reaction produced. Neutron and
unstable radioactive isotopes, radioactive isotopes produced in positron decay process.
The whole process is actually divided into 3 parts. The first is the gamma ray caused by lightning,
The whole process is actually divided into 3 parts. The first is the gamma ray caused by lightning,
which lasts for less than 1 milliseconds.
After calculating and analyzing the data found that second neutrons generated the light nuclear
reaction is to absorb other particles in the atmosphere when a gamma ray afterglow, lasts about
tens of milliseconds. The third paragraph is met the electronic positron annihilation event lasted
for 1 minutes, which also resulted in the "gamma ray edition" the storm.
