    The average lifetime of an excited atomic state is typically expressed in terms of its decay rate or the inverse of its decay constant. This decay rate is represented by the symbol γ (gamma) and is defined as the probability of the excited state decaying per unit time.

    In atomic physics, the average lifetime (τ) of an excited state can be calculated using the formula:

    τ = 1/γ

    If we assume that the decay rate (γ) is equal to 1/10, then the average lifetime (τ) of the excited atomic state would be:

    τ = 1/(1/10) = 10 units of time.

    Therefore, the average lifetime of the excited atomic state is 10 units of time.
