Scientific paper

IN a recent paper, Waddell and Slaughter1 suggested that the composite feature at 8668.43 Å in the solar spectrum includes a high excitation line of B I. This line is one of a number first reported in the laboratory spectrum of B I by Gunnvald and Minnhagen2 (Table 1). From the observed central depth of 0.015, a boron: hydrogen ratio of 4.0 × 10-7 was deduced. The terrestrial ratio3 is 7.6 × 10-10, while Russell's4 photospheric upper limit is 1.1 × 10-7. This figure was later reduced by Babcock5 to 2.8 × 10-8.
