From 2020 to 2021, as part of the HiCARI project, high-resolution in-beam $$gamma$$-ray spectroscopy experiments were conducted at the Radioactive Isotope Beam Factory. Using a collaboratively constructed array of 12 composite Ge detector systems, excitation state half-lives through Doppler-shifted spectroscopy were measured to investigate various physical phenomena. Specifically, we analyzed the Doppler-shifted line shapes of specific spin transitions and decays in $$^{131}$$In, $$^{131}$$Sn, and $$^{136}$$Te, characterizing the array and establishing reliable analytical methods. The obtained half-lifes were compared with existing experimental results and theoretical calculations.
