The undated diagram that was given to the AP by officials of a country critical of Iran's atomic program allegedly calculating the explosive force of a nuclear weapon _ a key step in developing such arms. The diagram shows a bell curve and has variables of time in micro-seconds and power and energy, both in kilotons _ the traditional measurement of the energy output, and hence the destructive power of nuclear weapons. The curve peaks at just above 50 kilotons at around 2 microseconds, reflecting the full force of the weapon being modeled. The Farsi writing at the bottom translates "changes in output and in energy released as a function of time through power pulse" (AP Photo)
