Abstract
A tuneable dye laser saturated absorption measurement of three of the fine-structure components of the Balmer alpha line of atomic hydrogen in a gas discharge yields a value of 10, 973, 731.513(85) m-1 for the Rydberg constant. The number in parenthesis is the uncertainty in the last digit quoted. It represents a standard deviation which is obtained by combining the random (0.021 m-1) and systematic (0.082 m-1) uncertainties as the root sum of their squares.Keywords
