In this paper, we have studied in detail the relationship between the
field and atomic squeezing in a two-level system coupled to a boson mo
de under different initial conditions. Under resonance, we have found
that for proper parameters chosen, the squeezed atom call radiate a sq
ueezed field almost at all the times. The influence of non-resonant in
teraction or thermal photons on squeezing has also been discussed.
