aψ=19.34nm
aψ=16.32nm
aψ=15.48nm
aψ=14.77nm
If,
aψ=aψc=19.34nm
aψ=aψc=16.32nm
aψ=aψc=15.48nm
aψ=aψc=14.77nm
aψ=aψc=16.32nm
aψ=aψc=15.48nm
aψ=aψc=14.77nm
in which case we have,
n.43π(aψc)3=43π(aψn)3
where 1≤n≤77 and
aψc=aψn=1
That is to say, n small particles of radius aψc coalesce into a bigger particle of aψn.
aψn=3√n.aψc
where n=1,2,3,..77
If each of this particle is responsible for a spectra line then, a spectra series due to one type of particle will line up nicely on a y=3√n plot with a common scaling factor. An the maximum number of stable lines due to stable particle, observable or otherwise is 77 or 78. Unstable particles that grows beyond the plateau on the ψ vs r graph where ψ pinch off with decreasing force will also result in faint spectra line.
Just speculating.
