The relative probabilities of transitions in the zinc atom

Abstract

Summary In order to determine the relative transition probabilities (t.p.) of the zinc atom, we measured the intensities of lines and bands in the spectrum of a d.c. carbon arc in air with one electrode containing a mixture of ZnO and MgCO3 or MgO. In table I the relative intensities of the components within several triplets are given. These intensity ratios are in good agreement with the multiplet intensity rules. The mean values of the product of t.p. and statistical weight of the upper level for the measured singlet and triplet lines are shown in table II. In order to obtain the approximate absolute values in sec−1 the values of table II have to be multiplied by ca. 4,6 . 105.
