  The relation is studied between the entanglement production and collective
radiation by an ensemble of atoms. Entanglement production is quantified by
means of a general measure introduced earlier by the author. Primary emphasis
is placed on the entanglement generated by pseudospin density matrices. The
problem of collective atomic radiation can be described by the pseudospin
evolution equations. These equations define the evolutional entanglement
generated by the related density matrices. Under conditions of superradiant
emission, the entanglement production exhibits sharp peaks at the delay time,
where the intensity of radiation is maximal. The possibility of regulating the
occurrence of such peaks by punctuated superradiance is discussed, which
suggests the feasibility of {\it punctuated entanglement production}.
