raie ultimen.

Brit.

/ˌreɪ ʊlˈtiːm/, U.S.

/ˌreɪ ʊlˈtim/

Inflections: Plural raies ultimes.

Origin: A borrowing from French. Etymon: French raie ultime.

Etymology: < French raie ultime (A. de Gramont 1907, in Comptes rendus hebd. de l'Acad. des Sci. 144 1101) < raie line, stripe, band (in a spectrum) (12th cent. in Old French, originally in sense ‘furrow’; apparently ultimately < an unattested Gaulish word cognate with Early Irish rech : see furrow n.) + ultime ultimate, last (see ultime adj.).The Gaulish word has also been borrowed into post-classical Latin as riga (c700), rega (late 8th cent.).

Physics.

An emission line in the spectrum of an element which is the last (or one of the last) to remain detectable as the concentration of that element decreases.

1937 C. Candler Atomic Spectra II. xvii. 120 As the proportion of calcium in the powder is diminished step by step, the weaker lines successively disappear until finally only one is left; this is known as the raie ultime.

1962 S. Walker & H. Straw Spectrosc. I. i. 94 The identification of the persistent (the raies ultimes) lines proves without doubt the presence of the corresponding element.

2005 C. E. Burkhardt & J. J. Leventhal Topics in Atomic Physics xiii. 274 Often, but not always, the raies ultimes are the ‘resonance lines’, that is, lines for which the lower state is the ground state.
