Precise fission fragment yield data are of great interest for a better understanding of the fission process. In a recent experiment, performed at the research reactor ILL Grenoble, Calorimetric Low Temperature Detectors (CLTDs) were applied for the first time for the investigation of Z-yield distributions of fission fragments. The concept of CLTDs, which is based on the collection of phonons, provides considerable advantage over conventional heavy ion detectors, based on charge collection, with respect to basic detector properties. Fission fragments, produced by thermal neutron induced fission of 235U, were passed through the LOHENGRIN separator to filter required mass and energy, followed by SiN degrader foils to separate elements with different Z within a mass, and were detected on an array of CLTDs. Preliminary data for the mass region 82<A<132 will be presented, which would lead to a better understanding of the fission process, as well as of reactor neutrino oscillations and the reactor neutrino anomaly.
