continuum emission
(continuous spectrum such as black-body radiation or bremsstrahlung)
A continuum emission is an emission of electromagnetic radiation
producing a range of wavelengths rather than a spectral line,
i.e., a continuous spectrum. Black-body radiation
is a ubiquitous mechanism. Others:
Two-photon emission is relaxation of atomic excitation
producing two photons instead of one. It occurs when
quantum-mechanical rules forbid the normal single-photon emission and
when frequent collisions are not inducing the relaxation,
specifically in low-density ionized gas.
