Referee's report by Nevill Francis Mott, on a paper 'The calculation of the absolute strengths of spectral lines' by David Robert Bates and Agnete Damgaard Sectional Committee: Physics No clear statement regarding publication in the Philosophical Transactions of the Royal Society. Has little experience with such computations, and does not know whats demands astrophysicists have for such methods. Assumes that such demands will be considerable, and the paper should be published somewhere, although it is very long. Suggests seeking the opinion of someone with more experience in the area, such as Douglas Rayner Hartree. [Published in the Philosophical Transactions of the Royal Society] No received date. [1948]
