Merging ab initio theory and few-body approach for reactions
J. Rotureau, G. Potel, W. Li +1
A new framework for reactions is introduced by merging the microscopic approach to computing the properties of the nucleon-target systems and the three-body react…
Toward a complete theory for predicting inclusive deuteron breakup away from stability
G. Potel, G. Perdikakis, B. V. Carlson +12
We present an account of the current status of the theoretical treatment of inclusive reactions in the breakup-fusion formalism, pointing to some applications and making th…
Role of core excitation in (d,p) transfer reactions
A. Deltuva, A. Ross, E. Norvaišas +1
[Background:] Recent work found that core excitation can be important in extracting structure information from (d,p) reactions. [Purpose:] Our objective is to systematically explor…
Examining the effect of nonlocality in transfer reactions
A. Ross, L. J. Titus, F. M. Nunes
Background: In the last year we have been exploring the effect of the explicit inclusion of nonlocality in (d,p) reactions. Purpose: The goal of this work is to extend previous stu…
Recent developments in the eikonal description of the breakup of exotic nuclei
P. Capel, F. Colomer, H. Esbensen +4
The study of exotic nuclear structures, such as halo nuclei, is usually performed through nuclear reactions. An accurate reaction model coupled to a realistic description of the pr…
Two neutron decay of 16Be
A. E. Lovell, F. M. Nunes, I. J. Thompson
Recently, the first example of two-neutron decay from the ground state of an unbound nucleus, Be, was seen. Three-body methods are ideal for exactly treating the degrees of…
Towards a Faddeev-AGS description of reactions with heavy nuclei: Regularizing integrals with Coulomb functions
The TORUS Collaboration, V. Eremenko, L. Hlophe +5
The repulsive Coulomb force poses severe challenges when describing reactions for highly charged nuclei as a three-body problem. Casting Faddeev-AGS equations in a Coulomb…
Testing the Perey Effect
L. J. Titus, F. M. Nunes
Background: The effects of non-local potentials have historically been approximately included by applying a correction factor to the solution of the corresponding equation for the…
Separable Representation of Phenomenological Optical Potentials of Woods-Saxon Type
L. Hlophe, Ch. Elster, R. C. Johnson +6
Background: One important ingredient for many applications of nuclear physics to astrophysics, nuclear energy, and stockpile stewardship are cross sections for reactions of neutron…
Mechanisms of direct reactions with halo nuclei
P. Capel, F. M. Nunes, H. Esbensen +1
Halo nuclei are exotic nuclei which exhibit a strongly clusterised structure: they can be seen as one or two valence nucleons loosely bound to a core. Being observed at the ridge o…
Status of reaction theory for studying rare isotopes
F. M. Nunes, N. J. Upadhyay
Reactions are an important tool to study nuclear structure and for extracting reactions relevant for astrophysics. In this paper we focus on deuteron induced reactions which can pr…
Asymptotic normalization of mirror states and the effect of couplings
L. J. Titus, P. Capel, F. M. Nunes
Assuming that the ratio between asymptotic normalization coefficients of mirror states is model independent, charge symmetry can be used to indirectly extract astrophysically relev…
Benchmark on neutron capture extracted from reactions
A. M. Mukhamedzhanov, F. M. Nunes, P. Mohr
Direct neutron capture reactions play an important role in nuclear astrophysics and applied physics. Since for most unstable short-lived nuclei it is not possible to measure the $(…
Scaling and Interference in the Dissociation of Halo Nuclei
M. S. Hussein, R. Lichtenthäler, F. Nunes +1
The dissociation of halo nuclei through their collision with light and heavy targets is considered within the Continuum Discretized Coupled Channels theory. We study the one-proton…
Core Transitions in the Breakup of Exotic Nuclei
N. C. Summers, F. M. Nunes, I. J. Thompson
An interesting physical process has been unveiled: dynamical core excitation during a breakup reaction of loosely bound systems. These reactions are typically used to extr…
Progress on reactions with exotic nuclei
F. M. Nunes, A. M. Moro, A. M. Mukhamedzhanov +1
Modelling breakup reactions with exotic nuclei represents a challenge in several ways. The CDCC method (continuum discretized coupled channel) has been very successful in its vario…
