DESCRIPTION:Speakers: Lefika Maphage (iThemba LABS/UCT)\nThis work present
 s a detailed investigation of high-spin states in $^{182}$W\, populated th
 rough a deep-inelastic reaction using an 840 MeV $^{136}$Xe beam on a thic
 k $^{186}$W target and studied using coincidence $\\gamma$-ray spectroscop
 y. Out-of-beam data were used to extend the known level scheme\, confirmin
 g the $K^{\\pi}$ = 16$^{+}$ rotational band up to the 19$^{+}$ state and i
 dentifying new levels feeding this structure. The study is motivated by th
 e need to understand how nuclear structure evolves at high angular momentu
 m. Several new intrinsic states have been observed up to 6549 keV\, includ
 ing an isomeric state with a lifetime of 148(9) ns. Spin and parity assign
 ments were derived from transition multipolarities using internal conversi
 on coefficients\, angular correlation and mixing ratios\, with most states
  firmly characterized\, including the 6549 keV state assigned $K^{\\pi}$ =
  24$^{-}$.\n\nNo new rotational bands were observed\, indicating a dominan
 ce of intrinsic configurations at high spin. Configuration assignments\, s
 upported by multi-quasiparticle calculations\, led to the identification o
 f several six-quasiparticle states with transition strengths consistent wi
 th neighboring nuclei in the A $\\approx$ 180 region. At high $K$-values\,
  weak transitions intensities limited the full characterization of some st
 ates\, however\, the long lifetime of the $K^{\\pi}$ = 24$^{-}$ isomer is 
 suggested to arise from configuration changes rather than $K$-forbidden de
 cay\, while $K^{\\pi}$ = 20$^{+}$ isomer shows behavior consistent with $K
 $-isomerism. Overall\, this work provides insight into the increasing domi
 nance of intrinsic structure over collective motion at high-spin in $^{182
