UV dominant optical emission newly detected from radioisotopes and XRF sources
M. A. Padmanabha Rao[tag, Brazilian Journal of Physics, vol. 40, no. 1, March, 2010, http://www.sbfisica.org.br/bjp/files/v40_38.pdf

(As excited atoms become free from surrounding unexcited atoms by valence excitation, room temperature atomic spectra of solid radioisotopes and XRF sources became a possibility. It implies existence of temporary atomic state of solids).
