Multichannel analyser for the neutron time-of-flight spectrometer

New multichannel time-of-flight spectrometer for the measurement of the energy and angular distributions of neutrons from the WWWR-M reactor is considered. This spectrometer has been developed for the replacement of the previous one to increase the number of channels and measurement precision, reduce the time of channel tuning and provide the automatic monitoring during the experiment

Interference Correlations of Hyperons in Neutron-Carbon Interactions

The interference correlations of \Lambda-hyperon pairs produced on the carbon target by 20-70 GeV neutrons have been investigated with the EXCHARM spectrometer. Destructive correlations at low relative 4-momenta are observed for \Lambda\Lambda-pairs. No correlations of this type are observed for \Lambda\bar{\Lambda}. Comparison with the corresponding data on meson correlations shows a decrease of production area sizes with an increase of particle masses
