摘要：

It has been demonstrated in the past that observing the β-decay spectrum of 187Re with microbolometers provides a suitable method to determine the mass of the electron anti-neutrino from β-endpoint measurements. In a first step, with the experiment MIBETA a sensitivity of mνe≤15 eV/c2 was achieved. To compete with the sensitivity of mνe≤2.2 eV/c2 established by the Mainz/Troitsk tritium β-decay experiment and the limit of mνe≤0.2 eV/c2 aimed at with KATRIN, a new experiment MARE has been initiated. As a first stage (MARE-1), 300 detectors consisting of silicon implanted thermistors, produced by NASA/GSFC, and absorbers of AgReO4 crystals will be mounted.
