Calculation Cross-section Rate

Click For Summary

There is a need for online resources to learn about calculating cross-sections and rates using Convergent-Close Coupling (CCC) methods. Specifically, users are seeking guidance on calculating the dissociation rate of molecular hydrogen ions influenced by electrons and ions. The discussion highlights a gap in accessible numerical methods and coding resources for these calculations. Participants are encouraged to share any relevant tutorials or coding examples that can assist in this area. Finding comprehensive educational materials on CCC is essential for advancing understanding and application in this field.

Is there an online source where I can learn how to calculate cross-sections and rates using CCC? More specifically, I want to calculate the dissociation rate of the molecular hydrogen ion due to electrons and ions, but I don't know how to do it numerically. Is there a resource available where I can learn the code to do this?

Thread 'Wave properties of a phonon'

I am currently reading Kittel's Introduction to Solid State Physics and am confused by the terminology regarding phonons. On page 99 (8th ed.), regarding Eq. 27, Kittel writes: "The energy of an elastic mode of angular frequency ## \omega ## is ## \epsilon = (n + 1/2)\hbar\omega ## when the mode is excited to quantum number ## n ##; that is, when the mode is occupied by ## n ## phonons. This definition implies that: The mode (the harmonic oscillator) is the entity that possesses the wave...
