We are a team of scientists and developers working at the Department of Experimental Physics, Faculty of Science, Palacký University in Olomouc.

 

Our mission and passion is application and development of nuclear physical technique mainly Mössbauer spectroscopy. In that we benefits from long term (since 80ties of 20th century) experiences in this area (see list of  publications). Selling of our spectrometers for costumers (universities and industry) ensure us the financing for next development and upgrading our equipment to get better results and better equipment for next research and our costumers.

 

Our team consists of people working in material research, nono-research focusing on the synthesis of functioning magnetic particles iron ferrites iron oxides, plasmonic structures, metaloorganic frameworks etc. We benefits also from close cooperation with chemical departments at aour university and also abroad.  We are not limited to the development of the standard equipment but we are working also in the field of Nuclear quantum optics with a radioactive source of 57Co, focusing on polarized Mössbauer spectroscopy, observing single photon entanglement and nonlocality of photons.

 

All these activities make us hard working on the optimization and improving of our devices and it keeps it up to date and on the highest level of knowledge.

 

Except our equipment we offers also a customize development of the equipment, measurement procedures and scientific collaboration.
