The international cooperation of the Nuclear Physics Group at Sari University has long been eliminated that the atomic nucleus of Lead-208 (²⁰⁸PB) has completely canceled. The discovery challenges the basic assumptions of nuclear structure and has far -reaching effects on our understanding of how the most heavier elements in the universe are formed.
Lead-208 is exceptionally stable as it is a “double magic” nucleus-which is the heaviest we know. However, a new study Published in Physical review messages I used a highly accurate experimental probe to examine its shape and found that instead of being completely spherical, the Lead-208 nucleus is slightly stretched, similar to the PROTHER SPHEROID.
“We managed to combine four separate measurements using the most sensitive experimental equipment in the world for this type of study, which allowed us to make this difficult note. Nuclear theory, presentation An exciting way to research in the future.
Using the Gretina Gamma-Ray’s moderate on the latest model in the National ARGONNE Laboratory in Illinois, the United States, scientists bombed bullets with high-speed speed-speed particles to 10 % of the speed of light-equivalent to rotate the Earth every second. The unique fingerprint reactions of gamma rays were created for the properties of the enthusiastic quantum cases in the Lead-208 cores-in other words, the cores-which in turn were used to determine their shape.
Theoretical physicists, including those in Surrey Nuclear Theory, re -examine the models used to describe atomic cores, as experiments indicate that the nuclear structure is more complex than previously thought.
“These very sensitive experiences have given a new light on something that we thought we were well understood, and we offer us the new challenge of understanding the reasons that Lead-208’s vibrations, when they are excited during experience Less regularly than before.
The study, which brought together a team of experts from nuclear physics research centers throughout Europe and North America, challenges the basic principles of nuclear physics and opens new ways to research nuclear stability, astronomical physics and quantum mechanics.
