Optimized binning for response function reconstruction via Chebyshev expansions
Immo C. Reis, Joanna E. Sobczyk, Sonia Bacca
We propose an optimized histogram binning strategy to reconstruct nuclear response functions via the Chebyshev expansion bound-state method. Our approach employs a stochastic regul…
16O electroweak response functions from first principles
Bijaya Acharya, Joanna E. Sobczyk, Sonia Bacca +2
We present calculations of various electroweak response functions for the 16O nucleus obtained using coupled-cluster theory in conjunction with the Lorentz integral transform metho…
Revisiting the helium isotope-shift puzzle with improved uncertainties from nuclear structure corrections
Simone Salvatore Li Muli, Thomas R. Richardson, Sonia Bacca
Measurements of the difference between the squared charge radii of the helion (He nucleus) and the -particle (He nucleus) have been characterized by longstanding tension…
Magnetic dipole transition in Ca
B. Acharya, B. S. Hu, S. Bacca +3
The magnetic dipole transition strength of Ca is dominated by a single resonant state at an excitation energy of 10.23 MeV. Experiments disagree about and th…
O spectral function from coupled-cluster theory: applications to lepton-nucleus scattering
Joanna E. Sobczyk, Sonia Bacca
We calculate the O spectral function by combining coupled-cluster theory with a Gaussian integral transform and by expanding the integral kernel in terms of Chebyshev polyno…
