Abstract
The dynamical correlation function, , of liquid germanium at 1500°C is obtained from the Fourier transform using experimental
. The limiting value for time to zero of
was compared with experimental
. From this result, the validity of present
is confirmed. From the result of
, the value of correlation of
located between
and
decreases up to around 0.8 psec and increases as time increases afterwards. From this fact, the result of
suggests that, especially in the short range of time, the single free particle behaviour is relatively included in the collective motion of germanium ions at this radius region.
