Abstract

Superconducting Analyzer for MUlti particles from Radio Isotope beams (SAMURAI) is an advanced spectrometer at RIKEN for experiments in which complete kinematic is determined to derive invariant-mass spectroscopy and parallel momentum distribution. This report represents the basic structure and technical advantages of SAMURAI, which was utilized in the third campaign of the “Shell Evolution An Search for Two-plus energies At RIBF” (SEASTAR3) project. Besides, particle identification corrections at the SAMURAI will be discussed. These corrections are a typical and crucial step in the data analysis process in SEATAR3 experiments. The particle identification results will be applied to analyze further a spectroscopic study on neutron-rich nuclei around N = 32, 34.
