Abstract Experiments on homogeneous initiation of pulsed avalanche discharges in typical XeCl laser mixtures show that the x-ray preionization pulse remains effective after a time delay of the order of 20 μs even at very high gas pressures (∼15 atm). Detailed kinetics analyses indicate that dissociative attachment of HCl is relatively slow during and after the preionization period so that the long effective delay time cannot be attributed to the storage effect of Cl− ions. Instead, the observed phenomenon can be attributed to the long survival time of the free electrons due to relatively slow diffusion and electron-ion recombination. Some problems arising from quantitative interpretation of the experimental results are also noted and discussed.
