Nuclear Stability03:18

Nuclear Stability

24.0K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Radioactivity and Nuclear Equations03:18

Radioactivity and Nuclear Equations

28.9K
Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The nucleus of an atom is composed of protons and, except for hydrogen, neutrons. The number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element.
A nuclide of an element has a specific number of protons and...

Nuclear Binding Energy02:13

Nuclear Binding Energy

15.1K
The difference between the calculated and experimentally measured masses is known as the mass defect of the atom. In the case of helium-4, the mass defect indicates a “loss” in mass of 4.0331 amu – 4.0026 amu = 0.0305 amu. The loss in mass accompanying the formation of an atom from protons, neutrons, and electrons is due to the conversion of that mass into energy that is evolved as the atom forms. The nuclear binding energy is the energy produced when the atoms’ nucleons are bound...

Nuclear Fission02:50

Nuclear Fission

12.8K
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large...

Nuclear Overhauser Enhancement (NOE)01:06

Nuclear Overhauser Enhancement (NOE)

1.6K
Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...

Nuclear Transmutation03:20

Nuclear Transmutation

20.9K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

Area of Science:

  • Nuclear astrophysics
  • Complex networks

Background:

  • Nuclear reaction networks are typically analyzed using differential equations, focusing on nuclide properties like half-life.
  • Existing research often overlooks the network structure of nuclear reactions.

Purpose of the Study:

  • To apply multilayer and reaction network methods to nuclear reactions.
  • To visualize nuclear reactions from the JINA REACLIB database as a directed network.
  • To explore the relationship between network topology and nuclear properties.

Main Methods:

  • Constructed a 4-layer directed network (neutron, proton, Helium-4, remainder) representing nuclear reactions.
  • Analyzed network topological features such as node degree difference and overlapping coefficient.
  • Incorporated reaction rates as node strengths.

Main Results:

  • Identified a strong correlation between beta-stability and topological characteristics in the remainder layer.
  • Found that nuclide half-life is reciprocally related to node out-strength at lower temperatures.
  • Demonstrated the utility of network theory in understanding nuclear physics.

Conclusions:

  • The network approach provides a novel perspective on nuclear reaction systems.
  • Topological properties of the nuclear reaction network are linked to fundamental nuclide characteristics.
  • This framework may aid in exploring the limits of the nuclide chart.
