    "abstract": "A second quantised theory of electrons and positrons in a deep time-dependent\npotential well is discussed. It is shown that positron production from the well\nis a natural consequence of Dirac\u0027s hole theory when the strength of the well\nbecomes supercritical. A formalism is developed whereby the amplitude for\nemission of a positron of a given momentum can be calculated. The difference\nbetween positron production and electron-positron pair production is\ndemonstrated. Considerations of the vacuum charge and of Levinson\u0027s theorem are\nrequired for a full description of the problem.",
