Abstract
Models of unified fundamental interactions suggest the existence of many particles in the mass range 10 x 109 to 100 x 1012 electron volts. Among these may be charged particles, X±, that are stable or nearly so. The X+,s would form superheavy hydrogen, while the X–,s would bind to nuclei. Chemical isolation of naturally occurring technetium, promethium, actinium, protactinium, neptunium, or americium would indicate the presence of superheavy particles in the forms RuX–, SmX–, 232ThX–, 235,236,238UX–, 244PuX–, or 247CmX–. Other substances worth searching for include superheavy elements with the chemical properties of boron, fluorine, manganese, beryllium, scandium, vanadium, lithium, neon, and thallium.Keywords
