Internal Conversion
Metastable isomers may also decay by internal conversion — a process in which the energy of nuclear de-excitation is not emitted as a gamma ray, but instead used to accelerate one of the inner electrons of the atom, so that it leaves at high speed and energy. This process is only possible because inner atomic electrons penetrate the nucleus, where they are subject to the intense electric fields which result when the protons of the nucleus re-arrange in a different way. In nuclei which are far from stability in energy, still other decay modes are known.

Famous quotes containing the words internal and/or conversion:
“We have our difficulties, true; but we are a wiser and a tougher nation than we were in 1932. Never have there been six years of such far flung internal preparedness in all of history. And this has been done without any dictator’s power to command, without conscription of labor or confiscation of capital, without concentration camps and without a scratch on freedom of speech, freedom of the press or the rest of the Bill of Rights.”
—Franklin D. Roosevelt (1882–1945)
“The conversion of a savage to Christianity is the conversion of Christianity to savagery.”
—George Bernard Shaw (1856–1950)
