Psi4's radii can be found at: https://github.com/psi4/psi4/blob/b4a272f74b73df8cf0edc4096081a250c495d55e/psi4/src/psi4/libfock/cubature.cc#L111
They just use H's radius for He. The use 3.3 a.u. whenever it isn't available.
add an error message to nan
after the rollback if exists
The following example will cause the becke partitioning to use Nan radii. The resulting grid gives large integration errors but not
Nans
:Output:
The resulting grid is not usable, so it would be safer to raise an exception when trying to construct becke weights with atoms for which the radii ar not defined.
