    "abstract": "The comparison of different models (the Ore, spur and blob models) of\npositronium (Ps) formation is presented. Because in molecular media Ps is\nformed in the terminal positron blob and not in an ordinary spur, the\napplication of the blob model seems to be the most adequate. We extend this\nmodel for consideration of the Ps formation in the presence of external\nelectric field ($\u003c100$ kV/cm). In the simplified limiting case, this approach\nprovides a formula similar to the Onsager one for the geminate recombination\nprobability. The influence of ion-electron recombination and other intrablob\nprocesses on Ps formation is taken into account. The role of quasifree\npositronium in Ps formation process is discussed.",
