“…In the latter case, no level scheme is reported, and a tentative assignment of I π = (25/2 + ) and a three-nucleon-hole character for the microsecond isomer was proposed. Projectile-fragmentation reactions have been utilized to identify and study isomers in a number of neutronrich isotopes like 204 Pt, 205 Au, and many in the Ta-Hg and Pt-Rn regions, including several even-A Pb nuclei [13][14][15][16][17]. The motivation for the present work was to obtain unambiguous information on the structural aspects mentioned above in order to advance the understanding of the structure of 203 Tl.…”
