TL;DR

This paper reviews theoretical models for direct nuclear reactions involving weakly-bound nuclei, discussing standard and extended frameworks for elastic, inelastic, transfer, and breakup reactions, including Coulomb excitation of halo nuclei.

Contribution

It provides a comprehensive overview of models tailored for weakly-bound nuclear systems, highlighting extensions beyond standard frameworks.

Findings

Standard models for weakly-bound nuclei reactions are summarized.

Extensions and alternative models are discussed for specific reaction types.

Application of semiclassical Coulomb excitation theory to halo nuclei breakup is included.

Abstract

In this contribution, I present a short overview of the theory of direct nuclear reactions, with special emphasis on the case of reactions induced by weakly-bound nuclei. After introducing some general results of quantum scattering theory, I present specific applications to elastic, inelastic, transfer and breakup reactions. For each of them, I first introduce the most standard framework, followed by some alternative models or extensions suitable for the case of weakly bound nuclei. A short discussion on semiclassical theory of Coulomb excitation and its application to breakup of halo nuclei is also provided.
