We present an ab initio study of the isoscalar monopole excitations of (4)He using different realistic nuclear interactions, including modern effective field theory potentials. In particular we concentrate on the transition form factor F(M) to the narrow 0(+) resonance close to threshold. F(M) exhibits a strong potential model dependence, and can serve as a kind of prism to distinguish among different nuclear force models. Compared to the measurements obtained from inelastic electron scattering…

Do light nuclei exhibit 'collective' motions?
The Lorentz integral transform (LIT) method has allowed to perform ab initio calculations of the response function of 4,6 He, and 6,7 Li to the isoscalar monopole and isovector dipole operators in a
Transition form factor of the $^4$ He(0+) monopole resonance
Electron-scattering-experiments offer an insight into nuclear structure and the involved nuclear forces. During the last years, a lot of effort and progress was made by including 3and 4-body terms in
Testing microscopically derived descriptions of nuclear collectivity: Coulomb excitation of 22Mg
Abstract Many-body nuclear theory utilizing microscopic or chiral potentials has developed to the point that collectivity might be studied within a microscopic or ab initio framework without the use
Quantum Monte Carlo calculations of light nuclei using chiral potentials.
The results confirm the necessity of a three-body force for correct reproduction of experimental binding energies and radii, and pave the way for studying few- and many-nucleon systems using quantum Monte Carlo methods with chiral interactions.
Implementation of Local Chiral Interactions in the Hyperspherical Harmonics Formalism
With the goal of using chiral interactions at various orders to explore the properties of the few-body nuclear systems, we write the recently developed local chiral interactions as spherical
Relativistic effects in ab-initio electron-nucleus scattering
The electromagnetic responses obtained from Green's function Monte Carlo (GFMC) calculations are based on realistic treatments of nuclear interactions and currents. The main limitations of this
Resolution of resonances with the Lorentz integral transform
The energy resolution of cross sections calculated with the Lorentz integral transform (LIT) method is investigated. It is shown that a crucial role is played by the density of LIT states obtained in
Removing center of mass effects in response function and sum rule calculations based on the harmonic oscillator basis
Response functions are at the heart of any comparison of theory with experiment in studies of the nuclear dynamics with electroweak probes. Calculations performed in the laboratory frame often suffer
The Hyperspherical Harmonics Method: A Tool for Testing and Improving Nuclear Interaction Models
The Hyperspherical Harmonics (HH) method is one of the most accurate techniques to solve the quantum mechanical problem for nuclear systems with a number of nucleons A ≤ 4. In particular, by applying
Ab initio calculations for non-strange and strange few-baryon systems
Concerning the non-strange particle systems the low-energy excitation spectra of the three- and four-body helium isotopes are studied. Objects of the study are the astrophysical S-factor S12 of the
