Abstract
The specific heat of polycrystalline α-uranium has been measured between 4.2 and 80 K. In addition to the second-order transition at 43 K, always seen in both polycrystalline and single-crystal uranium, a small effect was observed at 22 K. This had previously been seen only in single crystals. The larger, first-order change seen at 37 K in single-crystal uranium was not observed. The possible explanations for this difference are discussed.
