High-sensitivity delayed-coincidence spectrometer to search for short-lived nuclear states

A high-sensitivity four-dimensional triple-coincidence spectrometer with two detectors is developed on the basis of an autocorrelation single-crystal scintillation time 4 π spectrometer and a semiconductor HPGe detector. The delayed-coincidence spectrometer is designed to search for isomeric nano- a...

Description
Summary:A high-sensitivity four-dimensional triple-coincidence spectrometer with two detectors is developed on the basis of an autocorrelation single-crystal scintillation time 4 π spectrometer and a semiconductor HPGe detector. The delayed-coincidence spectrometer is designed to search for isomeric nano- and micro-second states in short-lived nuclei and for their related γ-rays. Half-lives of short-lived states are measured in the range from 4 ns to 4 μs. The sufficient activity of the monoisotopic source for the investigations does not exceed 0.01 μCi.
