V . The Structure Factor Reflections from crystals can occur only if all the unit cells
scatter in phase and the structure factor for a particular reflection is a complex OO

A . THE PHASE PROBLEM The obstacle to using Eq . ( 7 ) to obtain an electron
density map of a protein crystal is that although the structure amplitude | F ( hkl ) |
can readily be measured , the phases a ( hkl ) cannot be determined directly from
