Electron-positron pair production
The pair production is one
of the most interesting demonstrations for the presence
of
space matter in atoms. When a gamma ray photon with
an energy of 1.022 MeV or more, is passed through near a
heavy atomic nucleus (i.e., through the innermost
transitory shell), it can result the production of one
electron and one positron. The space matter density in
these regions is sufficient for the production of
electron - positron pair, when energetic gamma rays
passes through them. Because of the high-density, the
quantity of space matter in these regions is equal to or
more than the mass of the pair. When such an energetic
gamma ray photon is passed through them, the individual
space matter units in the region will be bonded together
to produce the pair. When a pair production occurs, the
equal amount of space matter (with the mass of the pair)
will be entered from outside of the atom and the
densities of the space matter in the atomic shells will
be always maintained.
