Abstract

In atomic spectroscopy, an important exploitation of the high sensitivity of laser enhanced ionisation (LEI) is in the experimental observation of extremely weak transitions such as forbidden lines. This paper reports on the LEI study of the intercombination line of magnesium 3s(2-)1S(0) - 3s3p3-P(0,1) at 457.110nm, which has an absorption oscillator strength of 4 x 1.0 E-6 and a spontaneous transition probability of 430/s. An atmospheric pressure flame such as the air-acetylene flame used provides a well-characterised, versatile atom reservoir for many elements.
