Is there the wavefunction of the collection of non-interacting n
electrons and M(m) noninteracting nulclei [m-number of
identical nuclei of type M]? For example two electrons and two nuclei
of different sort.

For the non-interactng electrons it's of course known - the Slater
determinant. For
the electrons-nuclei collection this is the combination of products of
single particle wave functions antisymmetrized wrt the transpositions
of identical particles.

But is there a compact and universal representation (similar to the
Slater determinant)?

Look forward at your suggestions.
