THERMAL EXPANSION OF INDIUM
Swenson 1955.
Hidnert and Blair 1943.
In the two investigations above, the experimental
methods and sample purities were
very similar. Yet the two points by Hidnert
and Blair, (L273 - L &/ L and (L -

Swenson's corresponding points. Swenson's
data have been adopted solely because they
include more points over .a wider temperature
range .
