Description

ERICCa (Eikonal Reaction, density Input, Cross section Calculator) is a Python package for calculating nucleus-nucleus reaction cross sections within the eikonal approximation framework. The code provides a flexible and robust approach to computing reaction observables by taking nuclear density distributions as direct inputs, allowing for accurate modeling of a wide range of nuclear reactions.

Key Features

• Eikonal Framework: Employs the two-body eikonal framework for fast computation of reaction cross sections
• Density-Based Approach: Nuclear density distributions (matter or proton and neutron densities) as inputs
• Accurate Integration: Implements multi-dimensional numerical integration with adaptive mesh configurations
• Validated Results: Benchmarked against experimental reaction data

Capabilities

ERICCa can calculate:

• Reaction cross sections using matter densities and proton and neutron densities as inputs and a profile function
• Automatic density generation based on rms matter radius and mass number
• Built-in profile functions for Energies 40-1000 MeV
