# Structure of resonances in a simple quantum-mechanical model

## TL;DR

This paper investigates the nature of quantum resonances using an exactly solvable model, introducing the concept of resonance form factors and analyzing resonant amplitudes through energy-dependent potentials.

## Contribution

It presents a novel analysis of resonance structures in quantum mechanics using an exactly solvable model, including the formulation of resonance form factors.

## Key findings

- Resonance form factors can be defined within this model.
- Resonant amplitudes are effectively described by energy-dependent potentials.
- The model provides insights into the structure of quantum resonances.

## Abstract

We study the structure of resonances derived from the solution of an exactly solvable Lippmann-Schwinger equation. Within this framework, we discuss the concept of "resonance form factors", and the description of the resonant amplitudes in terms of effective energy-dependent potentials.
