   <hidden TTP96-07  CP violation and CKM phases from angular distributions for $B_s$ decays into admixtures of CP eigenstates > We investigate the time-evolutions of angular distributions for 
 $B_s$ decays into final states that are admixtures of CP-even 
 and CP-odd configurations. A sizable lifetime difference between 
 the $B_s$ mass eigenstates allows a probe of CP violation in 
 time-dependent untagged angular distributions. Interference effects 
 between different final state configurations of $B_s\rightarrow D^{*+}_s\,
 D^{*-}_s$, $J/\psi\,\phi$ determine the Wolfenstein parameter $\eta$ 
 from {\it untagged} data samples, or -- if one uses $|V_{ub}|/|V_{cb}|$ 
 as an additional input -- the notoriously difficult to measure CKM 
 angle $\gamma$. Another determination of $\gamma$ is possible by 
 using isospin symmetry of strong interactions to relate {\it untagged} 
 data samples of $B_s\to K^{\ast+}\,K^{\ast-}$ and $B_s\to K^{\ast0}\,
 \overline{K^{\ast0}}$. We note that the {\it untagged} angular 
 distribution for $B_s\to\rho^0\phi$ provides interesting information 
 about electroweak penguins.
