Congratulations to Vladimir Morozov and Natalia Morozova on obtaining a patent!

Vladimir Aleksandrovich Morozov and Natalia Vladimirovna Morozova, employees of Sector No. 1 of Nuclear Radiation Spectrometry of the Scientific and Experimental Department of Nuclear Spectroscopy and Radiochemistry at the Laboratory of Nuclear Problems of the Joint Institute for Nuclear Research, have become the authors of a patent for the invention "Method for measuring the lifetime of excited states of nuclei using a 4π-scintillation single-crystal time spectrometer for fast and delayed coincidences."

The invention belongs to the field of charged particle delayed coincidence spectrometers that register radiation from a radioactive preparation, particularly single-detector fast-slow delayed coincidence spectrometers for determining the lifetimes of short-lived nuclear or molecular states. The spectrometer is characterised in that signals for time analysis are taken from the anode and the last dynode of the photoelectron multiplier using a device in which an additional load resistance is introduced into the circuit of the last dynode.

Technical specification: to implement a highly efficient single-detector fast-slow delayed coincidence spectrometer designed to determine the lifetimes of both nanosecond and microsecond excited states of radioactive nuclei by using low-activity sources in a 4π-measurement geometry.
