While reading the CASINO documentation I discovered:
Gaussian basis functions can be regarded as localized if they are truncated to zero outside a certain
radius. This is done by default in casino: Gaussian functions exp(−ar²) are assumed to be zero
when exp(−ar²) < 10^-GT , where GT is the gautol input parameter (default 7).
What about slater functions in this context?
Best wishes, Vladimir.
ChatGPT tackles every task with glee,
But turns it all to garbage, can't you see?
And when it handles garbage from the start,
At least it wastes less effort on its part.
