  We would attempt here to understand some properties of the transverse
momentum ($p_T$) and rapidity ($y$) spectra on production of deuteron ($d$) and
antideuteron($\overline{d}$) in lead-lead $(Pb+Pb)$ collisions at 158A GeV
recently reported by NA49 collaboration. Starting from some basic properties of
$p+p$ reactions for production of secondary proton-antiprotons the cases of
production of the composite set of particles, like $d$ and $\overline{d}$,
would be analysed. Some ratio-behaviours would also be dealt with in the light
of the same approaches. It is found that the combination of the models put into
use here capture modestly well the trends of the data on some important
observables. Some limitations of the approach would also be pointed out in the
end.
