本文对从金属镓单晶的Weissenberg照片中获得的新数据，用电子密度在（100）面上的投影和广义投影加以修正。由此获得的修正位置参数为y = 0.1549：i：：0.0008和z = 0.0810：i：：0.0006。镓原子的最近邻原子是2.484 A。2.691 A、2.730 A和2.788 A各两个。这些距离进行了讨论的金属键理论的鲍林。它的结论是，在镓金属中，每个原子形成一个单键和六个额外的键的顺序在0.3和0.5之间。
New data obtained from Weissenberg photographs of single crystals of metallic gallium have been refined by projeetions and generalized projections of the electron density on (100). The revised positional parameters thus obtained are y = 0.1549 :i:: 0.0008 and z = 0.0810 :i:: 0.0006. The closest neighbors of a gallium atom are one at 2.484 A. and two each at 2.691 A, 2.730 A, and 2.788 A. These distances are discussed in terms of the metallic bond theories of PAULING. It is concluded that in gallium metal each atom forms one single bond and six additional bonds of order between 0.3 and 0.5.
