Abstract
THE a and b lattice constants of gallium (orthorhombic, D182h—Abma) are almost identical and have often been a source of confusion, as has recently been emphasized by Yaqub and Cochran1. Diffractometer data at 4.2° K (ref. 2) (gallium of 99.9999 per cent grade) indicated a = 4.5156 Å, b = 4.4904 Å, c = 7.6328 Å, but at 297° K it appeared that a is smaller than b (in disagreement with Bradley3), and therefore that at an intermediate temperature (near 255° K) a should become equal to b.
