Atomic Nuclei: Nuclear Spin State Population Distribution01:14

Atomic Nuclei: Nuclear Spin State Population Distribution

1.7K
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.

Atomic Nuclei: Nuclear Magnetic Moment

3.0K
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...

Atomic Radii and Effective Nuclear Charge

48.6K
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

1.3K
An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...

Atomic Nuclei: Nuclear Spin State Overview

1.8K
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of one, the...

Atomic Nuclei: Nuclear Relaxation Processes

1.1K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis,  the precessing magnetic moments are randomly oriented around the z-axis.

Area of Science:

  • Nuclear Physics
  • Atomic Nuclei Structure

Background:

  • Advanced methods like the generator coordinate method (GCM) excel in describing collective motion in even-even nuclei.
  • Current state-of-the-art GCM uses angular-momentum and particle-number projected triaxially deformed Hartree-Fock-Bogoliubov (HFB) states.
  • Extending these methods to odd-mass nuclei remains a significant challenge in nuclear physics.

Purpose of the Study:

  • To develop and present a novel extension of GCM for odd-mass nuclei.
  • To build the generator coordinate space using self-consistently blocked one-quasiparticle HFB states.
  • To validate the new method by applying it to ^{25}Mg.

Main Methods:

  • Utilizing self-consistently blocked one-quasiparticle HFB states to construct the generator coordinate space.
  • Employing the same Skyrme interaction for both mean-field and pairing channels to ensure Pauli principle compliance.
  • Applying angular-momentum and particle-number projection techniques.

Main Results:

  • The developed method successfully describes the nuclear spectrum, electromagnetic moments, and transition strengths for ^{25}Mg.
  • Accurate agreement with experimental data was achieved for both positive and negative parity states.
  • The method eliminates the need for effective charges or effective moments in calculations.

Conclusions:

  • This work presents the first successful extension of GCM to odd-mass nuclei.
  • The method demonstrates the potential for systematic description of odd-A nuclei across the nuclear chart.
  • Further refinement of the effective interaction is suggested for improved accuracy.
