We developed KEK Isotope Separation System (KISS) for the nuclear spectroscopy of the nuclei in the vicinity of N = 126. The spectroscopy is important to identify the explosive astrophysical environment for the formation of the third peak in the observed solar r -abundance pattern. We report the experimental results of in-gas-cell laser ionization spectroscopy and β -decay spectroscopy for the nuclei in the vicinity of 198 Pt.
