bound-bound transition		Transition between energy levels of an electron bound to a nucleus (the electron is bound both before and after the transition).	atomic physics		world point	atomic process
emission	intensity	The process of transition of an electron from an outer orbit to an inner orbit around the nucleus results in a characteristic amount of energy being radiated (as line emission) that corresponds to the lost energy of the electron.	optics	absorption		radiation intensity modification
spontaneous emission	intensity	Radiation emitted by an isolated body.	atomic physics	absorption	world point		emission
