Event Analysis in Nuclear Emulsion for the E07 Experiment at J-PARC Myint Kyaw Soe Endo, Yoko Hoshino, Kaoru Ito, Hiroki Itonaga, Kazunori Kobayashi, Hidetaka Khin Than Tint Kinbara, Shinji Mishina, Akihiro Yoshida, Junya Nakazawa, Kazuma Hammer track events in nuclear emulsion were analyzed to measure the excitation energy of 8Be* (2+) nucleus. The kinetic energies of two alpha particles of hammer track events were obtained from their ranges with use of range-energy relation. The range-energy relation was calibrated by measuring the alpha particle tracks emitted from 212Po of Thorium decay series in the emulsion. From this calibration, we obtained density and shrinkage factor of the emulsion. The excitation energy and width of 8Be* (2+) nucleus were measured to be 3.39 ± 0.24 MeV and Γ = 1.22 ± 0.60 MeV respectively. 2015 http://hdl.handle.net/20.500.12678/0000000577 https://meral.edu.mm/records/577
