    "abstract": "We theoretically investigate the possibility for a tetraneutron to exist as a\nlow-energy resonance state. We explore a microscopic model based on the\nassumption that the tetraneutron can be treated as a compound system where\n$^3$n+n and $^2$n+$^2$n coupled cluster configurations coexist. The influence\nof the Pauli principle on the kinetic energy of the relative motion of the\nneutron clusters is shown to result in their attraction. The strength of such\nattraction is high enough to ensure the existence of a low-energy resonance in\nthe tetraneutron, provided that the oscillator length is large enough.",
