of the polarization moments of the density matrix

General inequalities for the relaxation constants of polarization moments are examined. Concrete numerical limitations for the
values of these constants are obtained.
In recent years it has been generally accepted to
characterize the distribution of the angular momen-
tum j of atomic as well as molecular states in the
framework of the irreducible tensorial operators
PG. The state is described by means of polarization
moments p& which are the expansion coefficients of
the angular momentum density matrix pm,,,,on the
tensorial operators pz:
Polarization moments have a very clear physical
meaning. Thus a moment with rank K=O charac-
terizes the population of the level, with X= 1the ori-
entation, and with K=2 the alignment [ I].
