✦ Synopsis

The one-particle density in momentum space ␥ p is studied for diatomic molecules by using the maximum-entropy technique. The knowledge of one or more momentum ² n : Ž . expectation values p provides approximations on the density ␥ p for any value of the momentum, which are convergent when increasing the number of known moments. Other unknown expectation values are estimated in terms of the constructed maximumentropy densities. A numerical study of the quality of the approximations is carried out by means of experimental and theoretical data for the momentum expectation values involved. Experimental errors are also taken into account to have an idea of the sensibility of the results to the information from which they are obtained.

Spectral analysis is an important method by which the variation in a data set can be decomposed into waves of different frequencies. In the form of the power spectral density it is usually estimated directly from the data using the fast Fourier transform which often requires considerable pre-process
