Homework Help Overview

The discussion revolves around the concept of selection rules in quantum mechanics, particularly how they apply to transitions between quantum states. Participants are exploring the implications of these rules on the allowed changes in quantum numbers during such transitions.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to clarify the nature of selection rules and their role in determining allowed transitions between quantum states. There is a focus on understanding the relationship between quantum numbers and transition probabilities.

Discussion Status

The discussion is ongoing, with some participants providing insights into the nature of selection rules and their applications. There is an indication of interest in further exploring related concepts, such as the Wigner-Eckart theorem, suggesting a productive direction for the conversation.

Contextual Notes

There may be assumptions about prior knowledge of quantum mechanics and the specific context in which selection rules are applied, which could influence the depth of understanding among participants.

could someone explain the selection rule and how it's used?
 
Physics news on Phys.org
It's selection rules, not just a rule. When you calculate the transition probability between two quantum states labeled by the relevant quantum numbers the selection rules tell you which transitions are allowed. In other words the rules tell you how the quantum numbers are allowed to change in transitions between states.
 
thank you!
 
Check out applications of Wigner-Eckart theorem.
