Abstract

In this paper we present resonance experimental results performed on spin-10 Fe8 molecular clusters to elucidate the so called Schrödinger's cat paradox. We explain theoretically that the resonances detected in the millikelvin regime correspond to transitions between the symmetric and antisymmetric combinations of the degenerate ground state with {Sz{ = 10. The back and forth quantum tunnelling oscillations of the spin are superimposed during a time lower than 10-7 sec.
