; PROJECT:  CHIANTI
;
;       CHIANTI is an atomic database package for the calculation of
;       continuum and emission line spectra from astrophysical plasmas. It is a 
;       collaborative project involving the Naval Research Laboratory
;       (Washington DC, USA), the Arcetri Observatory (Firenze, Italy), and the
;       Cambridge University (United Kingdom).

;
;
; OUTPUTS:
;
;	Name:  the spectroscopic notation for the ion, i.e. 'Fe II'
