摘要：
It is pointed out that if the molecular interpretation of the recently observed resonance X(3872) is valid, then nature may have prepared a good laboratory for us to examine the phenomenon of superradiance and subradiance of Dicke. The superradiance and supradiance factors are evaluated and the effects on the electromagnetic radiative decay of X(3872) are discussed. Our results using coordinate space representation is similar to the momentum space results of Voloshin.
