X-ray diffraction measurements on a recently discovered crystalline form of La revealed that La crystallizes in a body-centered cubic lattice in which the unit cell edge length is 426.3 picometers. Compute the atomic radius of the La atoms in this crystal based on the normal assumption that the atoms are tightly packed in the unit cell.
