Abstract
The COBRA experiment is going to use a large amount of CdZnTe semiconductor detectors to perform a search for various double-beta-decay modes. The current status of the experiment is presented, as well as first results. Improved half-life limits for the ground-state transitions of 64Zn and 120Te for 0νβ +/EC and 0νECEC have been obtained and the rate of the 4-fold forbidden 113Cd decays has been measured. A short outlook on future activities is also given.
