Scientists create weird pumpkin-shaped nucleus that vanishes in nanoseconds

Physicists in Finland have created a pumpkin-shaped atomic nucleus that throws off protons in a unusual form of radioactive decay. 

The nucleus, lutetium-149, has the shortest 50 percent-lifetime of any of a team of radioactive features known as proton-emitters, according to PhysicsWorld (opens in new tab). It loses half its radioactivity (decays into other components) in a mere 450 nanoseconds, the physicists claimed March 16 in the journal Bodily Overview Letters (opens in new tab)
