Abstract:
The calculated band positions and intensity factors for the bands of the infrared A-X transition of A10 suggest that an investigation for the infrared bands in the 1 to 5 micron region of the spectra of Mira stars and M supergiants, along with the 'blue-green' (B-X) bands, could provide clues to the Mira phenomena. The need for additional laboratory investigation of the infrared electronic transition is emphasized
