A 1s Slater-type function is a mathematical function used in quantum chemistry and atomic physics to describe the spatial distribution of electrons in an atom, particularly for the innermost shell of electrons (the 1s orbital). Slater-type orbitals (STOs) are defined by their exponential decay and can be used to effectively approximate the wavefunctions of electrons.
