摘要: Abstract We investigate deuteron formation in nuclear matter at finite temperatures within a systematic quantum statistical approach. consider through three-body collisions relevant already rather moderate densities because of the strong correlations. The in-medium reaction rates driven by break-up cross section are calculated using exact equations (Alt–Grassberger–Sandhas type) that have been suitably modified to consistently include energy shift and Pauli blocking. Important quantities lifetime fluctuations chemical relaxation time. find respective times differ substantially while or isolated sections. expect implications for description heavy ion particular light charged particles low intermediate energies.
