Abstract
|
|
|
|
| We apply inverse moment techniques to analyse certain time dependent autocorrelation functions. The experimentally measured values are interpreted as moments of a probability distributionf(x) which is calculated numerically. For this purpose we use Chebychev's algorithm. By means of the inverse algorithm we can reproduce the original data within numerical precision. The ill-conditioning of the inverse moment problem is circumvented by making an ansatz for the unknown higher order moments. We discuss in particular exponentially and algebraically decaying correlation functions. |
