These compounds, produced by organic decay, can cause photon emissions.

A clear transition from electron to photon emission is evident in this chart for increasing atomic number.

Single photon emission computed tomography shows focal and global hypoperfusion (75% cases)

Various photon emissions follow, as the energy of the atom falls to the ground state of the new nuclide.

The spectrum of photon emission is narrow, characterized by its full width at half the maximum value.

The photon histogram records an increase in photon emissions during times that the transistor switches on or off.

However, searches for direct photon emission from the low-lying excited state have failed to report an unambiguous signal.

Well, the easy part is what is different about the electron before and after photon emission.

On the isolated species this excitation can usually only decay slowly by photon emission.

Such sources have already been demonstrated with quantum dots by controlling their photon emission with various schemes.
