The superconductivity is a very important quantum phenomenon occurring in many materials. However the microscopic origin of it is still not completely understood and is one of the most significant challenges in condensed matter physics. Recently the coexistence of superconductivity and charge- and/or spin-density waves attracted a renewed interest since it is believed to be fundamental to our understanding behind the mechanism of superconductivity.Here we plan to perform a detailed muSR study on a single crystal of type-II V3Si superconductor in order to investigate the possible presence of a charge density wave ordering phenomenon occurring in the normal state well above the superconducting transition. This study is complementary to nuclear magnetic resonance results that we have recently obtained, which are compatible with the presence of a charge density wave below 200 K.
