The Ca I absorption spectrum has been photographed between 10 and 120 angstrom for the first time. At least seven discrete features-all attributable to excitation of the 2p subshell - have been observed. Identifications are made by comparison with Ha

New observations of the absorption spectrum of Mn I between 1800 and 700 Å have revealed 77 new transitions, arrangeable in Rydberg series converging on to experimentally known levels of the ion. The analysis of the spectrum at wavelengths shorter t

A method is derived to determine spectral series limits analytically. It is assumed that the graphical quantum defect solution (n−n* vs νlim−ν) is approximately linear (for the correct νlim) so that a least-squares fit may be obtained. The pro

New observations of the 5p spectra of Cs i and Ba i are reported. The extreme complexity of the structure does not permit precise configuration labels to be attached to all the excited levels. Nevertheless, more than 160 transitions in Ba i have been

In this paper we present evidence that the ‘164-day’ period in the wavelengths of the ‘moving’ lines in SS 433 has been decreasing at the surprisingly rapid rate of P = −0.010±0.002. An ephemeris of the moving lines for the 1981 observing

We present a model which provides an interpretation of the observations relating to the object SS433. The model represents the logical development of the proposal of Collins and Newsom (1979) and consists of a binary system comprised of a massive ear

The vacuum ultra-violet absorption spectrum of calcium vapour was observed in an attempt to discover transitions to new energy levels. Seven new levels have been found between 51 000 and 59 000 cm-1, three of which are ascribed to the 3d5p, 3d6p and

The spectrum of strontium has been re-examined within the range 2100 AA to 26000 AA. A large number of new lines have been observed and many of these are diffuse. This has led to the identification of new energy levels including the even parity autoi
