  When a weak decay competes with a strong decay in a 3-level atom, some
mechanism is necessary to occasionally stop the strong decay so the weak decay
can be completed. Rule (4) provides that mechanism. Using this rule, a weak
photon is emitted at the correct time for both the V and L configurations, as
well as for the two cascade configurations. Key Words: observer, detector,
measurement, florescent pulsing, probability current, state reduction,
three-level atom.
