Determination of the width of the absorption line of atomic iodine in optimization of the parameters of an iodine switch

A theoretical basis is given for the optimization of the parameters of an iodine switch. The results are reported of an experimental study of the pressure dependence of the width of the absorption line of atomic iodine. The broadening coefficient of molecular iodine is 3.2 MHz/Torr in the temperature range 800–1000 °C.
