Details of the identification of $^{186}\mathrm{Tl}$ and its decay to $^{186}\mathrm{Hg}$ as investigated with an isotope separator are presented. Conversion electrons, $\ensuremath{\gamma}$, $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$, and $e\ensuremath{-}\ensuremath{\gamma}$ studies establish two bands in $^{186}\mathrm{Hg}$; one built on a near-spherical ground state and one on a more strongly deformed shape with a band head at 522 keV. The levels are discussed in the framework of recent theoretical calculations.RADIOACTIVITY $^{186}\mathrm{Tl}$, $^{186}\mathrm{Tl}^{m}$ from $^{181}\mathrm{Ta}(^{16}\mathrm{O},11n)$, $E=145$ MeV; $^{182}\mathrm{W}(^{14}\mathrm{N},10n)$, $E=168$ MeV; mass separated radioactivities. Measured ${T}_{\frac{1}{2}}$, ${E}_{\ensuremath{\gamma}}$, ${E}_{\mathrm{ce}}$, ${I}_{\ensuremath{\gamma}}$, ${I}_{\mathrm{ce}}$, $\ensuremath{\gamma}\ensuremath{\gamma}$ coin, $e\ensuremath{\gamma}$ coin, ICC, $^{186}\mathrm{Hg}$ deduced levels, $I$, $\ensuremath{\pi}$, multipolarities. |
