The Lorentz integral transform (LIT) method

TL;DR

The Lorentz integral transform (LIT) method transforms complex continuum problems into bound-state-like problems, enabling ab initio calculations for multi-particle nuclear reactions previously considered intractable.

Contribution

This paper reviews the LIT approach, highlighting its ability to simplify continuum problems and extend ab initio calculations to larger nuclear systems.

Findings

LIT reduces continuum problems to bound-state-like problems.

LIT enables calculations for systems with up to seven nucleons.

The method broadens the scope of ab initio nuclear reaction studies.

Abstract

The LIT approach is reviewed both for inclusive and exclusive reactions. It is shown that the method reduces a continuum state problem to a bound-state-like problem, which then can be solved with typical bound-state techniques. The LIT approach opens up the possibility to perform ab initio calculations of reactions also for those particle systems which presently are out of reach in conventional approaches with explicit calculations of many-body continuum wave functions. Various LIT applications are discussed ranging from particle systems with two nucleons up to particle systems with seven nucleons.
