Physicists in Finland have developed a kind of atomic nucleus that throws protons into a form of radioactive decay.
The nucleus, lutetium-149, contains the shortest part of one of a group of radioactive substances called proton-emitters, according to PhysicsWorld. It loses half of its radioactivity (decays on other materials) in about 450 nanoseconds, physicists reported on March 16 in the journal. Physical inspection messages.
Lutetium is a rare earth material that is found in its natural form as a silvery metal with 71 protons and 71 neutrons in its nucleus. It is usually produced with the metal ytterbium in it Earththe rubbish. In the 1980s, scientists discovered that an isotope of lutetium – a modified form of an atom with a different number of neutrons in the nucleus – was found to be lutetium -151, decaying and discarding. proton from its nucleus to its earth position. The state is the lowest level of energy available to the electrons of an atom and its most stable arrangement. Proton release is rare, and lutetium-151 is the first isotope known to release protons as it decays in its solid state.
Studying proton decay allows researchers to look inside the nucleus of an atom and understand how protons and neutrons interact. As part of this line of research, Kalle Auranen, a postdoctoral researcher in physics at the University of Jyväskylä, and colleagues created a new isotope of lutetium, lutetium-149, which has 71 protons. and 78 neutrons in its nucleus. They found that lutetium-149 was more valuable than lutetium-151. For one thing, it is not a clean circle, but an oblong circle like an aura. This is known as oblate distortion, and lutetium-149 is the most distorted nucleus measured.
Lutetium-149 has a shorter half-life of lutetium-151 of 80.6 milliseconds.
The researchers created the isotope by shooting an isotope of nickel, nickel-58, at an isotope of ruthenium, ruthenium-96, according to PhysicsWorld. The new lutetium isotope that depletes ytterbium-148 does not last long: It has a half-life of 250 milliseconds.
According to PhysicsWorld, lutetium-148 can form, which can last much longer than lutetium-149.
