Description
The goal of the project is to investigate the new effect consisting in fission fragment's brake-up while passing the solid-state foil. According to the previous experiments [1-3], it is expected that masses of some brake-up residuals correspond to magic nuclei such as $^{128,132}Sn$ and $^{144}Ba$. The project aims to detect in coincidence all the products of fragment's brake-up using the Timepix3 pixel detector. It permits simultaneous determination of (x, y) coordinates of the detected products with $\mu$m resolution as well as their energy and time-of-flight. Measurements of angular and energy correlations of the products are performed in FLNR (JINR) with thin source of $^{252}Cf(sf)$. Special software for searching for multibody decays were worked out and applied for processing of the experimental data already obtained. First results and problems arisen of using Timepix3 detectors will be reported.
