How to find angular momentum for spin 2 particle?

Click For Summary

Homework Help Overview

The discussion revolves around calculating the total angular momentum for a spin 2 particle within the context of quantum mechanics. Participants are exploring the relationship between spin and angular momentum, particularly focusing on the notation and values associated with spin 2 particles.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to understand how to calculate total angular momentum using the formula J(J+1)|j,m> and questions the steps involved. Other participants discuss the values of m_s for spin 2 particles and how they relate to total angular momentum.

Discussion Status

Participants are actively engaging with the problem, with some providing insights into the values of m_s and the implications for calculating Sz. There is a recognition of the complexity of the topic, and while no consensus has been reached, there is a productive exchange of ideas regarding the calculations involved.

Contextual Notes

There is an acknowledgment that the original poster's quantum mechanics textbook lacks examples for spin 2 particles, which may contribute to the confusion. Additionally, some participants reflect on the educational context, noting that quantum mechanics is typically not covered at the high school level.

My problem is with finding total angular momentum S of a spin 2 particles. My quantum book doesn't do any examples with spin 2 particles do i just do
J(J+1)|j,m> and just plug in j and that will be my value. By the way my book likes to skip a lot of steps so can someone explain how to do this.

Ok it is how you do it. does anyone know how to figure out Sz
 
Well,total angular momentum is spin+orbital and is traditionally denoted by "J".For spin 2 particles,the "s" is "2",while the "m_s" can take 5 possible values.

P.S.And,please,DO NOT double post.It so much annoys me to see things double. It's like i was drunk.

Ok I will do. I realized that no one in high school will be doing quantum in high school for a long time. so I had to change to college level. Thanks again so from what your saying S_z will have 5 different Values since M_s for a spin 2 has 5 values makes sense to me for a spin 1/2 it has 2 spin1 it has 3. Had an Idea just wanted someone to say your right.
