Recent inspections of the internal structure of the uncommon isotope ruthenium-88 bring new light on the internal structure of atomic nuclei, a discovery that might result in further insights into how some chemical elements in nature and their isotopes are shaped.
Guided by Bo Cederwall, Prof. of Experimental Nuclear Physics at KTH Royal Institute of Technology, a world research group recognized new rotational states in the extraordinarily neutron-deficient, deformed, atomic nucleus 88Ru. The outcomes suggest that the presence of strongly-paired neutron-proton pairs influences the structure of this unique nuclear system.
The outcomes may also counsel alternative explanations for how the production of various chemical components, and in particular their most neutron-poor isotopes, proceeds in the nucleosynthesis reactions in specific stellar environments similar to neutron star-red titan binaries, he says.
The breakthrough, which was featured February 12 in the journal, Physical Review Letters, results from an experiment at the Grand Accélérateur National d’Ions Lourds, France, applying the Superior Gamma Tracking Array (AGATA).
The researchers employed nuclear collisions to develop highly unstable atomic nuclei with equal numbers of neutrons and protons. T
heir structure was studied by utilizing delicate instruments, along with AGATA, detecting the radiation they emit in the form of high–power photons, neutrons, protons, and different particles.
Based on the Standard Model of particle physics describing the elementary particles and their interactions, there are two common types of particles in nature; fermions and bosons, which have an integer and half-integer spin, respectively.
