Detailed Description

Used to pass params to Integral::g12().

Represents (a pair of) linear combinations of exponentials: $
   \sum_i c_i \exp( - g_i x )
$ where $ x $ is $ r_{12}^2 $ for Gaussian geminals.

Member Function Documentation

◆ save_data_state()

void sc::IntParamsG12::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::IntParams.
