“…These potentials now also lead to elastic cross sections, or equivalently, phase shifts for each set of quantum numbers. We compare in table 2 the computed phase shifts with measured values from [28]. The s 1/2 and d 5/2 phase shifts are matching the data perfectly as expected because the positions of the bound states are well determined in our fits to match the measured values.…”

We investigate to what extent 18 Ne can be descibed as a three-body system made of an inert 16 O-core and two protons. We compare to experimental data and occasionally to shell model results. We obtain three-body wave functions with the hyperspherical adiabatic expansion method. We study the spectrum of 18 Ne, the structure of the different states and the predominant transition strengths. Two 0 + , two 2 + , and one 4 + bound states are found where they are all known experimentally. Also one 3 + close to threshold is found and several negative parity states, 1 − , 3 − , 0 − , 2 − , most of them bound with respect to the 16 O excited 3 − state. The structures are extracted as partial wave components, as spatial sizes of matter and charge, and as probability distributions. Electromagnetic decay rates are calculated for these states. The dominating decay mode for the bound states is E2 and occasionally also M 1.

We describe bound states, resonances and elastic scattering of light ions using a δ-shell potential. Focusing on low-energy data such as energies of bound states and resonances, charge radii, asymptotic normalization coefficients, effective-range parameters, and phase shifts, we adjust the two parameters of the potential to some of these observables and make predictions for the nuclear systems d + α, 3 He + α, 3 He + α, α + α, and p + 16 O. We identify relevant momentum scales for Coulomb halo nuclei and propose how to apply systematic corrections to the potentials. This allows us to quantify statistical and systematic uncertainties. We present a constructive criticism of Coulomb halo effective field theory and compute the unknown charge radius of 17 F.

“…In fact, in the literature a large number of separable potentials are available which have been found to work well in different energy regions and to depend on the relative angular momentum state of the scattering particle (for eg. see [44,45,46,47,48,49].…”

In this contribution we make a short review of recent progress on topics of current interest in nuclear physics and nuclear astrophysics. In particular, we discuss a re-analysis of the extraction of the dipole response of the pigmy resonance in $^{68}$Ni based on a continuum discretized coupled-channels calculation in relativistic Coulomb excitation experiments. We also discuss the forthcoming progresses made by our group on the Alt-Sandhas-Grassberber approach to (d,p) reactions and future expectations. The role of separable potentials in solving such equations with a test case based on applications of such potentials to phase-shift analysis is also presented.Comment: Carpathian Summer School of Physics 2016,Exotic Nuclei and Nuclear/Particle Physics VI, "Physics with small accelerators", eds.
