# Jastrow Information related to the Jastrow factor in trans-correlated calculations. The main keywords are: - `j2e_type` - `j1e_type` - `env_type` ## j2e_type Options 1. **None:** No 2e-Jastrow is used. 2. **Mu:** 2e-Jastrow inspired by Range Separated Density Functional Theory. It has the following shape:

with,

## env_type Options The 2-electron Jastrow is multiplied by an envelope \(v\):

- if `env_type` is **None**: No envelope is used. - if `env_type` is **Prod_Gauss**:

- if `env_type` is **Sum_Gauss**:

Here, \(A\) designates the nuclei, and the coefficients and exponents are defined in the tables `env_coef` and `env_expo` respectively. ## j1e_type Options The 1-electron Jastrow used is:

- if `j1e_type` is **None**: No one-electron Jastrow is used. - if `j1e_type` is **Gauss**: We use

are defined by the tables `j1e_coef` and `j1e_expo`, respectively. - if `j1e_type` is **Charge_Harmonizer**: The one-electron Jastrow factor aims to offset the adverse impact of modifying the charge density induced by the two-electron factor

- if `j1e_type` is **Charge_Harmonizer_AO**: The one-electron Jastrow factor **Charge_Harmonizer** is fitted by the atomic orbitals
