# Ion-Ion Correlation Effect on the Neutrino-Nucleus Scattering in Supernova Cores

@article{Itoh2004IonIonCE, title={Ion-Ion Correlation Effect on the Neutrino-Nucleus Scattering in Supernova Cores}, author={Naoki Itoh and Ryohei Asahara and Nami Tomizawa and Shinya Wanajo and Satoshi Nozawa}, journal={The Astrophysical Journal}, year={2004}, volume={611}, pages={1041-1044} }

We calculate the ion-ion correlation effect on the neutrino-nucleus scattering in supernova cores, which is an important opacity source for the neutrinos and plays a vital role in supernova explosions. In order to calculate the ion-ion correlation effect we use the results of the improved hypernetted-chain-method calculations of the classical one-component plasma. As in the preceding studies on this effect, we find a dramatic decrease of the effective neutrino-nucleus scattering cross section…
