The intermetallic Mo3Sb7 compound exhibits superconductivity at Tc=2 K and exhibits interesting physical properties in the magnetic susceptibility, electrical resistivity and point-contact (PC) Andreev-reflection. Remarkably, measurement of the specific heat points to the existence of two BCS-like gaps. Considering the similarity between superconducting Mo3Sb7 and unconventional superconductors (high-Tc-cuprates, Heavy-fermion), and interesting resonant magnetic excitation (observed resonance peak at 4.5-5*Tc) property of the latter materials, we propose here to investigate low energy inelastic neutron scattering response of Mo3Sb7 using the OSIRIS/IRIS spectrometer. We expect the resonance peak near 0.6 meV in Mo3Sb7 on the basis of finding in CeCoIn5 having similar TC=2.2 K the resonance peak is observed at 0.6 meV.
