Abstract: 

The Optical Time Projection Chamber (OTPC) detector was initially designed and constructed at the Warsaw University Physics Faculty to study two-proton transitions (2p). It did help to precisely study 2p emissions in 45Fe nuclei and to show that the involved process is in fact a three-body process. Discovery of a 2p emission in 48Ni nickel isotope was another important result obtained with the help of the detector. However, it turned out that the novel detector rendered itself very well suited to study other rare nuclear transitions accompanied by emissions of charged particles. For example, OTPC helped to observe for the first time emissions of three delayed protons in beta decay of three various nuclides. We have also successfully used it to take spectra of deuterons emitted in 6He beta decay.

After a brief outline of principles of operation of the OPTC detector, some most interesting results obtained with its help will be discussed. Some digital photographs of nuclear processes occurring in the discussed experiments taken by the detector will be shown.

The seminar will be held in Science & Technology Park building conference room in Świerk. NCBJ bus leaves to Świerk at 10.15 am from entrance gate to the 69 Hoża str. premises in Warsaw.
