TABLE I
Isotope shifts (in mK, 1 mK = 0.001 cm−1), of Kr i. The figures in parentheses are the standard deviations. The figures in square brackets, after the figures in parentheses, are the differences between the directly measured shifts between two adjacent even isotopes M and M − 2 and those given by the differences of the shifts 86 − (M − 2) and 86 − M
