Final answer:
X-ray diffraction, carried out using an X-ray diffractometer, is utilized to determine a single crystalline bcc metal's lattice parameter by interpreting diffraction patterns through the implementation of the Bragg equation.
Step-by-step explanation:
Yes, X-ray diffraction can be used to determine the lattice parameter of a single crystalline body-centered cubic (bcc) metal. The concept behind this technique is known as X-ray crystallography. An X-ray diffractometer can measure the angles at which X-rays are diffracted from a crystal. By applying the Bragg equation, which relates the diffraction angles to the distance between atomic layers, one can compute the lattice parameter, which is the repeat distance between atoms in the crystal lattice. This method of using diffraction patterns to study crystal structures played a pivotal role in the determination of the structure of DNA and is also fundamental in the research of complex materials like high-temperature superconductors.
