Which R and Angular Parts Create a 2p Wave for 2p to 1s Transition?

Click For Summary
SUMMARY

This discussion focuses on calculating the selection rules for the transition from the 2p to 1s quantum states in quantum mechanics. The user seeks to identify the specific radial (R) and angular components that contribute to the three distinct 2p wave functions, as referenced in results (1152)-(1154). The spherical harmonics factors are also mentioned as part of the analysis. The user successfully computes the y-component of the wave function but struggles with eliminating the $$\pm$$ sign in their final answer, which is detailed in result (1153).

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly selection rules.
  • Familiarity with spherical harmonics and their application in quantum states.
  • Knowledge of radial wave functions in quantum mechanics.
  • Ability to perform integrals involving quantum mechanical wave functions.
NEXT STEPS
  • Study the derivation of selection rules in quantum mechanics.
  • Learn about spherical harmonics and their role in angular momentum.
  • Explore radial wave functions for hydrogen-like atoms in quantum mechanics.
  • Practice integrating quantum mechanical wave functions to solidify understanding.
USEFUL FOR

Students and researchers in quantum mechanics, particularly those focusing on atomic transitions and wave function analysis.

sel rule int.png


I am trying to calculate the selection rules from 2p to 1s. Above are the three results in (1152)-.(1154). And In the image one also finds the spherical harmonics factors. I can not determine which R and angular parts that give the three 2p waves. Can you show which ones that will create one of the 2p waves and integrate the radial (radius part) part of that integral?

I get the right answer for the y comp except that I cn not get rid of the $$\pm$$. the answer for the y-comp is given in (1153).
