Large quanties of antimatter isolated from normal matter should behave exactly like normal matter. An antiatom, for example, composed of positrons, antiprotons, and antineutrons, should have the same atomic spectrum as its matter counterpart. 1. Would you be able to tell it is antimatter by its emission of antiphotons? Explain briey. 2. Describe how you could use a magnetic eld to trap antimatter, such as that produced by nuclear decay, and later combine it with matter to produce energy
