Abstract

The transition strengths have been calculated for transitions between configurations 5d8 6s and 5d8 6p of Au iii based upon the wavefunctions given by Shadmi. These strengths have been compared with the estimated intensities given by Iglesias and are found to be in substantial agreement.

Keywords: Au iii, calculated transition strengths, configurations 5d8 6s and 5d8 6p

1. Introduction

Shadmi [1] recently calculated the energy levels of the third spectrum of gold (Au iii) for the configurations 5d9 + 5d8 6s and 5d8 6p. He compared his calculations with the observations and classifications of Iglesias [2]. Shadmi found that the LS coupling assignments did not fit the levels of Au iii. Rather, the levels more closely fitted an intermediate coupling representation which could be fairly well approximated by a jj coupling scheme. From the description given by Shadmi, we calculated the transition array between the configurations 5d8 6s and 5d8 6p.

2. Theory

The strengths of the transitions are defined as in Condon and Shortley [3] by

S(A,B)=a,b|(a|P|b), (1)

where the sum is over all the states which form the sublevels of the levels A and B. We first calculate the square roots of the relative strengths between the two above mentioned configurations in the LS representation. We assume that the dipole approximation is valid, so that the transition operator is given by

P=jerj, (2)

where the sum is taken over the electrons involved in the transition. Except for a radial integral factor common to all the matrix elements of the transition array, the matrix elements can be readily calculated [4]. We define Tk to be the transformation matrix which transforms the energy matrix for the configuration K in the LS scheme to the representation where the energy matrix is diagonal, the desired representation. The matrix for the transition from configuration K to configuration K′ is then given by

M=TK+MLSTK, (3)

where, T+ is the hermitian conjugate of T.MLS is the matrix for the transition in the LS representation and M is the matrix in the required representation. In eq (3), we employed the same transformation matrices, TK and TK, that Shadmi used to diagonalize the energy matrices. The square roots of the relative strengths and their phases for the transition array d2s — d2p, which are the complements of the configurations under consideration here have been treated elsewhere [5] and were utilized for our calculations here.

We find that for the most part our calculated relative strengths agree fairly well qualitatively with Iglesias’s estimated intensities. Iglesias [6] revised some of the classified levels after Shadmi’s publication appeared. Some of the previously “unobserved” transitions with significant strengths (from these calculations) now coincide with observed lines. In table 1 we present for completeness the relative strengths for the complete transition array 5d86s – 5d8 6p in the intermediate coupling scheme. For each position in the array the upper line corresponds to the relative strength and the next line corresponds to the wavelength of the published lines. The lowest line gives the wavenumber of the transition.

Table 1. Relative strengths for complete transition array in the intermediate coupling scheme.

For each position in the array the upper line corresponds to the relative strength and the next line corresponds to the wavelength of the published lines. The lowest line gives the wave number of the transition. The various energy levels of the d8s and d8p configurations are identified by the dominant LS state with its percentage contribution to the state, (as calculated by Shadmi) as well as the observed energy level. Those energy levels in parentheses are calculated levels.

In table 2 we list the strengths as a function of wavelength. The wavelength is listed in the first column in angstroms, the wavenumber (in cm−1) is given in the second column for unreported transitions or for transitions which have been reclassified by Iglesias, the third and fourth column list the statistical weights for the lower and upper states respectively, and in the last column we list the strength of the transition. Transitions between one or more levels which have not been observed are not listed in this table.

Table 2. The calculated line strengths as a function of wavelength.

We list in the first column the wavelength in Å, in the second column the wave number in cm−1, in the third and fourth columns the statistical weights of the lower and upper states, and in the last column the relative strengths.

The wave numbers with an asterisk are the results due to the modification made by Iglesias [6].

The wavelengths with † are calculated values, others are observed.

The relative strengths are given in general to two decimal places on the scale where the radial integral factor is normalized to unity. The approximations in the present calculation would, for the most part, preclude any real significance to more decimal places. However, in table 1 we have included strengths which are less than 0.01 to indicate orders of magnitude. We have also included strengths which are less than 0.01 in table 2 only for those lines which have been observed. A strength with a value of 0.0 indicates that on our scale it is less than 5×10−5. In most cases we find that the larger values of the strengths correspond to the transitions observed by Iglesias. There are very few observed lines below 2000 Å with strengths less than 0.04. Beyond 2000 A there are only a few lines with strengths of the order of 0.001 or less. This indicates that the wave functions obtained by Shadmi are quite good and the identification of the energy levels is in substantial agreement with Iglesias’s revised classification.
