WebApr 25, 2003 · Physicists have long thought that bismuth-209 was stable. But as more precise measurements of mass became possible, theorists suggested that the heavy element should decay to become the element thallium-205, an alpha particle, and a packet of extra energy. Since the 1950s, researchers have tried to detect this decay, but with no …
