With the aim of finding an appropriate description of the state of an ejected electron from a linear three-centre molecular target, a wavefunction is constructed in a closed analytical form by solving the Schrödinger equation of an unbound electron (with wave vector k) in a Coulomb field of three fixed charged nuclei. The model, which is an extension of a two-centre model developed in the past, fulfils the correct boundary conditions asymptotically up to the order O((kr) −2 ). It is employed,
