<i>Ab</i><i> Initio</i> Calculation of the Alpha-Particle Monopole Transition Form Factor

We present a parameter -free ab initio calculation of the alpha-particle monopole transition form factor in the framework of nuclear lattice effective field theory. We use a minimal nuclear interaction that was previously used to reproduce the ground state properties of light nuclei, medium -mass nuclei, and neutron matter simultaneously with no more than a few percent error in the energies and charge radii. The results for the monopole transition form factor are in good agreement with recent precision data from Mainz.
