General Quantization of Motion in Circular Orbits

Click For Summary
SUMMARY

The discussion focuses on the general quantization of motion in circular orbits, specifically using the equations for potential energy U(r) and angular momentum quantization mvr = nℏ. The derived energy spectrum for circular motion in a potential U = F0r is expressed as En = 3/2*(n4/3ℏ4/3 F02/3 + F02/3 n2/3 ℏ2/3)/m1/3. The next step involves calculating the energy difference ΔE = hc/λ, which requires establishing an equation for the energy levels En+1 – En based on the derived formula.

PREREQUISITES
  • Understanding of classical mechanics and potential energy concepts
  • Familiarity with angular momentum quantization and the relation mvr = nℏ

NEXT STEPS
  • Explore the derivation of energy levels in quantum mechanics using the Schrödinger equation
  • Research the implications of the relation ΔE = hc/λ in quantum systems
  • Study the concept of quantization in different potential fields, such as harmonic oscillators
  • Investigate the application of circular orbits in quantum mechanics and their relevance in atomic models

For this question, I have to obtain a general quantization of motion in circular orbits by combining the equations (Where U(r) is potential energy):
(mv2)/r= |(dU(r))/dr|

With the angular momentum quantization of: mvr= nℏ

Then use this to calculate the spectrum for circular motion in a potential of U = F0r.

After combining these equations, along with E = Ke + Pe (for kinetic and potential energies), I obtained this equation:
En= 3/2*(n4/34/3 F02/3+F02/3 n2/32/3)/m1/3

The next step confuses me. To obtain a spectrum, I would have to use the relation ∆E=hc/λ; however this requires a difference of energies for ΔE. Would this mean setting up an equation for En+1 – En, using the equation I found for En?

Hello Witz and welcome to PF. There is a pretty strict rule here that you make use of the template. In this case even I can see the usefulness: you have to obtain a general quantization. That's what you have done, so you are finished.

Why contnue? What is triggering the spectrum adventure ?
(You have an idea, why not follow up on it?)
