High-resolution transmission electron microscopy (HRTEM) images are simulated for the core structures of 1/2[111] screw dislocations in body centered cubic (bcc) metals to examine the possibility of determining the core structure experimentally by HRTEM. Two types of cores are studied: a polarized c
