New emission branching fraction (BF) measurements for 183 lines of the second spectrum of chromium (Cr II) and new radiative lifetime measurements from laser
Keeley I. Townley-Smith, Gillian Nave, J C. Pickering, Richard J. Blackwell-Whitehead
We expand on the comprehensive study of hyperfi ne structure (HFS) in Mn II conducted by Holt et al. (1999) by verifying hyper fine magnetic dipole constants (A
The spectrum of singly-ionized iron (Fe II) has been recorded using high-resolution Fourier transform and grating spectroscopy over the wavelength range 900 Å
Stephen L. Redman, Gillian Nave, Craig J. Sansonetti
We have made precise new observations of the spectrum emitted by a thorium-argon hollow cathode lamp in the region 350 nm to 1175 nm using a high-resolution
Ritz wavelengths of 27 spectral lines of Fe II of have been derived from Fourier transform spectra. The lines selected are observable in absorption spectra from

We report accurate Ritz wavelengths for parity-forbidden [Ni ii] transitions, derived from energy levels determined using high-resolution Fourier transform
Christian Clear, Juliet Pickering, Gillian Nave, Peter Uylings, Ton Raassen
High-resolution spectra of singly ionized nickel (Ni II) have been recorded using Fourier transform spectroscopy in the region 143–5555 nm (1800–70,000 cm−1)
We report new experimental hyperfine structure constants of levels in neutral and singly ionized Scandium (Sc I & Sc II). We observed spectra of Sc-Ar and Sc-Ne
We report new observations of the infra-red (IR) spectrum of low current Th-Ar hollow cathode lamps with the 2-m Fourier transform spectrometer (FTS) at the
