    "abstract": "The formation of correlations due to collisions in an interacting nucleonic\nsystem is investigated. Results from one-time kinetic equations are compared\nwith the Kadanoff and Baym two-time equation with collisions included in Born\napproximation. A reasonable agreement is found for a proposed approximation of\nthe memory effects by a finite duration of collisions. This form of collision\nintegral is in agreement with intuitive estimates from Fermi\u0027s golden rule. The\nformation of correlations and the build up time is calculated analytically for\nthe high temperature and the low temperature limit. Different approximate\nexpressions are compared with the numerical results. We present analytically\nthe time dependent interaction energy and the formation time for Gau\\ss{}- and\nYukawa type of potentials.",
