Happy Birthday to me...03 Oct 1968.
If spectra lines reflect the collision and subsequent coalescence of particles, then the observation that more spectra lines appear at lower experiment setup temperature, can be explained by lower collisions rate at lower temperature with less momentum which allows bigger particles to form. Bigger particles have higher \(a_{\psi\,n}\) which appear as a higher spectra line. At higher temperature, big particles are broken up in high velocity impacts before further coalescence forms bigger particle.
So, at low temperature more spectra lines due to bigger particles appear.
Have a nice day.
