Isovector and Isoscalar magnetic moments

In summary, the Skyrme model is being studied to calculate the magnetic momenta of protons and neutrons. This is done by first calculating the isoscalar and isovector magnetic moments, but there is confusion on how these are connected to the baryon/isovector current and how to deduce the magnetic momenta of protons and neutrons. A suggested resource for further understanding is the book "Few-Body Problems in Particle, Nuclear, Atomic, and Molecular Physics" edited by Jean-Louis Ballot and Michel Fabre de la Ripelle. However, some pages of the book may not be accessible online.

Hi all,
I am currently working on the Skyrme model. In the paper of Zahed and Brown: "The Skyrme Model" which can be found online they want to calculate the magnetic momenta of protons and neutrons. They do this by first calculating the isoscalar and isovector magnetic moments(p.69). However, I first of all do not understand how these are connected to the baryon/isovector current and how one should deduce the magnetic momenta of proton/neutron from these.
Do you have any good book/textbook suggestion(which would ideally be found online;)?
Thanks so much in advance!
Bob

Thank you a lot- unfortunately a lot of the pages are not visible.
 

Related to Isovector and Isoscalar magnetic moments

1. What are Isovector and Isoscalar magnetic moments?

Isovector and Isoscalar magnetic moments are properties of a particle or nucleus that describe its magnetic dipole moment, which is a measure of its response to an external magnetic field. The isovector magnetic moment describes the strength of the particle's magnetic moment due to the difference in the number of protons and neutrons in its nucleus, while the isoscalar magnetic moment describes the strength of the magnetic moment due to the combined effect of both protons and neutrons.

2. How are Isovector and Isoscalar magnetic moments measured?

Isovector and Isoscalar magnetic moments are typically measured using experimental techniques such as nuclear magnetic resonance (NMR) or electron spin resonance (ESR). These techniques use the interactions between the magnetic moments of the particles or nuclei and an external magnetic field to determine their strengths.

3. What is the significance of Isovector and Isoscalar magnetic moments?

Isovector and Isoscalar magnetic moments are important properties in nuclear and particle physics as they provide important information about the structure and behavior of particles and nuclei. They can also be used to study the properties of different types of interactions between particles and to test theories and models of nuclear and particle physics.

4. How do Isovector and Isoscalar magnetic moments differ?

The main difference between Isovector and Isoscalar magnetic moments is that the isovector magnetic moment is sensitive to the difference in the number of protons and neutrons in a particle or nucleus, while the isoscalar magnetic moment is sensitive to the combined effect of both protons and neutrons. Additionally, the isovector magnetic moment can be either positive or negative, while the isoscalar magnetic moment is always positive.

5. Can Isovector and Isoscalar magnetic moments change over time?

Yes, Isovector and Isoscalar magnetic moments can change over time due to various factors such as changes in the composition of the particle or nucleus, changes in the external magnetic field, or interactions with other particles. These changes can be studied and measured using experimental techniques and can provide valuable insights into the properties and behavior of particles and nuclei.
