Fine-tunings in radiative $\alpha$-particle capture on ${}^{12}$C at astrophysical energies

Ulf-G. Meißner, Bernard Ch. Metsch, Helen Meyer

We investigate the fine-tuning of radiative alpha-particle capture on carbon, $\alpha {(}^{12}\mathrm{C}{,}^{16}\mathrm{O})\gamma$, at astrophysical energies. Utilizing results from cluster effective f…
