|Abstract:||An extensive 237-Np Moessbauer study of the new Np4Ru7Ge6 compound is reported. This material reveals only a pure axial symmetric quadrupole interaction down to 4.2 K and its isomer shift points to the occurrence of a Np3+ charge state. A careful analysis of the intensities of the hyperfine lines shows the presence of an absorber thickness effect and an Einstein type model fits well the temperature dependence of the isotropic lattice vibrations. The non-magnetic ground state inferred from the in-field measurements may be understood within the Kondo lattice/RKKY model. The observation of an enhanced susceptibility at low temperature may indicate a heavy fermion behaviour.|
