## Detailed Description

R12IntEval is the top-level class which computes intermediates occuring in linear R12 theories.

This class is used by all Wavefunction classes that implement linear R12 methods.

## Constructor & Destructor Documentation

sc::R12IntEval::R12IntEval | ( | const Ref< R12IntEvalInfo > & | info,
|  | bool | gbc = `true`,
|  | bool | ebc = `true`,
|  | LinearR12::ABSMethod | abs_method = `LinearR12::ABS_CABSPlus`,
|  | LinearR12::StandardApproximation | stdapprox = `LinearR12::StdApprox_Ap`,
|  | bool | follow_ks_ebcfree = `false` |
| ) |  |  |

Constructs R12IntEval.

If follow_ks_ebcfree is true then follow formalism of Klopper and Samson to compute EBC-free MP2-R12 energy.

## Member Function Documentation

void sc::R12IntEval::save_data_state | ( | StateOut & |  | ) | `[virtual]`

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them.

This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.
