Contribution
It introduces spectral functions for medium-sized nuclei and demonstrates their applicability to neutrino cross section calculations.
Findings
Spectral functions for calcium and argon match quasielastic electron scattering data.
Argon spectral function successfully predicts neutrino-nucleus cross sections.
Validation of spectral functions enhances modeling of neutrino interactions.
Abstract
The spectral functions for calcium and argon are constructed. It is verified that their predictions for the quasielastic electron-nucleus cross sections in the energy range ~1 GeV agree with the data. The argon spectral function is then used to obtain the quasielastic neutrino-nucleus cross section.
