 Tutored Practice Problem 12.2.3 Determine d-spacing and radius from a scaltering

Tutored Practice Problem 12.2.3 Determine d-spacing and radius from a scaltering angle. Gold metal crystallizes in a face centered cubic lattice with one atom per latice point Monochromatic X-radiation froma Zin tarjet has a wavelength of 143.6pm. If this radiation is used in a diffraction experinent with a gold crystal, a second order diffracted beim is observed at a theta valtie of 20.62. If the spacing between these planes corresponds to the tuit cell length (d=m, what is the d-spacing berweeu the platei that gave rise: to this reflection? What is the metallic radins of a gold atom? d-spacing=radius=pmpm
