UrduProtons and neutrons orbit atomic nuclei in shells with caps on how many protons or neutrons they can hold. Full shells mean stable, compact nuclei. Physicists call the number of protons or neutrons in a “magic” numbered full shell. New research shows that a previously reported “magicity” for number 32 does not appear in neutron-rich potassium isotopes.

Scientists Further Their Investigation into the Origin of Elements in the Universe
The slow neutron-capture process (the s-process) in nucleosynthesis results in about half of the elements heavier than iron in the universe. Two important reactions in the s-process are Neon-22 (alpha, gamma) and Neon-22 (alpha, neutron), which affect the abundances of elements such as Selenium, Krypton, Rubidium, Strontium, and Zirconium. Researchers recently used two indirect methods to study the reactions.

Signs of “Turbulence” in Collisions that Melt Gold Ions
A new analysis of collisions of gold ions shows signs of a “critical point,” a change in the way one form of matter changes into another. The results hint at changes in the type of transition during the shift from particles to the quark-and-gluon “soup” that filled the early universe. This helps scientists understand how particles interact and what holds them together.
