Write down the ground configuration of calcium (Z = 20). The line
at 610nm in the spectrum
of neutral calcium consists of three components at relative
positions 0, 106 and 158 (in units of cm−1). Identify the terms and
levels involved in these transitions. The spectrum also contains a
multiplet of six lines with wavenumbers 5019, 5033, 5055, 5125,
5139 and 5177 (in units of cm−1). Identify the terms and levels
involved. Draw a diagram of the relevant energy levels and the
transitions between them. What further experiment could be carried
out to check the assignment of quantum numbers?
