  Using a renormalized linked-cluster-expansion method, we have extended to
order $\beta^{23}$ the high-temperature series for the susceptibility $\chi$
and the second-moment correlation length $\xi$ of the spin-1/2 Ising models on
the sc and the bcc lattices. A study of these expansions yields updated direct
estimates of universal parameters, such as exponents and amplitude ratios,
which characterize the critical behavior of $\chi$ and $\xi$. Our best
estimates for the inverse critical temperatures are
  $\beta^{sc}_c=0.221654(1)$ and $\beta^{bcc}_c=0.1573725(6)$. For the
susceptibility exponent we get $\gamma=1.2375(6)$ and for the correlation
length exponent we get $\nu=0.6302(4)$.
  The ratio of the critical amplitudes of $\chi$ above and below the critical
temperature is estimated to be $C_+/C_-=4.762(8)$. The analogous ratio for
$\xi$ is estimated to be $f_+/f_-=1.963(8)$. For the correction-to-scaling
amplitude ratio we obtain $a^+_{\xi}/a^+_{\chi}=0.87(6)$.
