# Form of power spectrum to dirac delta function?

The power spectrum of a delta function is a constant, independentof its real space location. It is given by|F{delta(x-a)^2}|^2=|exp(-i2xpiexaxu)|^2=1.

# If a photon is the product of the Dirac annihilation energy of a virtual electron-positron pair how is the energy dispersed?

In mutual annihilation, a positron and an electron combine. and the masses of both particles are entirely converted into energy. The energy is divided between not one but two ( Full Answer )

# What becomes of the hole in the Dirac Sea is it considered an open slot for other electrons seeking a negative state of energy or is the positron assumed a negative state of energy by itself?

Theory allowed for the existence of negative energy states, which was a bit of a philosophical problem, since if these existed electrons should all fall into the lower energy ( Full Answer )
