E. Charters, let have our terminology all the same. Last time I used these fancy pieces of equipment, the SEM was a scanning Electron Microscope. You have to be gifted to get resolution betwer than .1 micron or a thousand Angstrom. A cluster of 64 atoms will have a diameter of about 40 Angstrom (or .004 Angstrom), well below the detection limit of traditional SEM. You may be referring to the atomic force microscope, it is not really a chemical analyzer, it is a super sensitive surface profiler and once you know you have a cluster, it will show you its general geometry (this the tunneling type microscope you are refering to, it used to be called that and now they have changed the name to atomic force microscope, I know not why). By the way, using this to analyze ores of any kind would be like using a 16" marine gun to soot down a fly. Zeev PS, I have never used an atomic force microscope myself, so if someone on the thread knows differently, please do not hesitate and correct me. I have used an SEM quite extensively.
