Using the Transition-Density Formalism in the First Computation of 4He Compton Scattering
Harald W. Griesshammer, Junjie Liao, Judith A. McGovern +2
The method and results of the first theory description of 4He Compton scattering at nuclear energies is presented, with a focus on figures. An upcoming publication [1] contains det…
Compton Scattering on 4He with Nuclear One- and Two-Body Densities
Harald W. Griesshammer, Junjie Liao, Judith A. McGovern +2
We present the first \emph{ab initio} calculation of elastic Compton scattering from 4He. It is carried out to [N3LO] in the expansion of EFT. At this…
Calculation of Dynamical Response Functions Using a Bound-state Method
Niels R. Walet, Jagjit Singh, Johannes Kirscher +3
We investigate a method to extract response functions (dynamical polarisabilities) directly from a bound-state approach applied to calculations of perturbation-induced reactions. T…
Scattering Observables from One- and Two-Body Densities: Formalism and Application to He Scattering
Harald W. Griesshammer, Judith A. McGovern, Andreas Nogga +1
We introduce the transition-density formalism, an efficient and general method for calculating the interaction of external probes with light nuclei. One- and two-body transition de…
Designing Optimal Experiments: An Application to Proton Compton Scattering
J. A. Melendez, R. J. Furnstahl, H. W. Griesshammer +3
Interpreting measurements requires a physical theory, but the theory's accuracy may vary across the experimental domain. To optimize experimental design, and so to ensure that the…
Polarisabilities from Compton Scattering on 3He
Harald W. Griesshammer, Judith A. McGovern
This executive summary of recent theory progress in Compton scattering off 3He focuses on determining neutron polarisabilities; see ref. [2] and references therein for details and…
