Abstract
EVANS et al.1 (see also refs 2, 3) have presented data on the rate of production of 37Ar with the Brookhaven Solar Neutrino Detector; two facts stand out: the overall mean rate is low compared with expectation4, and one run, No. 27, may be significantly higher than the remainder. The present note is primarily concerned with the statistical significance and explanation of this high rate. The calculation of the rates and uncertainties is not a simple procedure and it is important to have an independent determination; with the cooperation of the authors, we have made our own analysis using their basic data (β-ray counter measurements of the β-activity of the abstracted 37Ar over successive periods of ∼30 d), for the important run 27.
