2026-07-27 Raw and processed experimental data for hydrogen-isotope emission in the spontaneous fission of 252Cf doi:10.57760/sciencedb.42101 en This dataset contains processed experimental and calculated data used in the investigation of hydrogen-isotope emission accompanying the spontaneous fission of ²⁵²Cf with a Timepix-based ΔE–E telescope.The experimental telescope consisted of a thin silicon ΔE detector and a single Timepix hybrid pixel detector. The Timepix detector simultaneously operated as the residual-energy detector, denoted as E, and as a position-sensitive pixel detector. Thus, the same detector provided both deposited-energy information and two-dimensional pixel-cluster information for each detected event.The experimental data were processed using energy calibration, event synchronization, cluster reconstruction, particle-selection criteria, and ΔE–E identification cuts. The ROOT files contain processed ΔE–E spectra and associated analysis objects obtained after application of the full set of event-selection cuts. The files are separated according to the measurement or analysis periods identified by month in the filenames.Each ROOT file contains processed data from both telescope detectors, including the measured energy loss in the ΔE detector, residual energy measured by the Timepix detector, ΔE–E particle-identification distributions, and analysis results obtained after applying the selected data-quality and particle-identification cuts.The dataset also includes talys_proton_energy_spectrum.ods, which contains the calculated proton-energy spectrum for the ²⁷Al(α,p) reaction obtained using the TALYS nuclear-reaction code. These calculated data were used to evaluate the contribution of proton-producing reactions involving alpha particles and aluminium and to support interpretation of the measured proton-energy distribution.The experimental uncertainties arise mainly from detector energy resolution, calibration accuracy, electronic noise, counting statistics, event-selection criteria, and the boundaries used for particle identification. The calculated TALYS results additionally depend on the selected reaction-model parameters, nuclear-data libraries, and computational settings.The files may be reused for charged-particle identification, comparison of ΔE–E selection procedures, validation of detector-response simulations, analysis of proton, deuteron, and triton emission, and comparison between experimental spectra and nuclear-reaction model calculations. ternary fission; ∆E–E method; Timepix pixel detector; ∆E detector; silicon detector; protons; deuterons; tritons; alpha particles Ahmadov Gadir Berikov Daniyar Ahmadov Farid Nuruyev Sabuhi Nuruyev Sabuhi Sadygov Azer Holik Michael Chuprakov Igor Mendibayev Kairat Zholdybayev Timur PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
