  The Morse potential is relatively closed to the harmonic oscillator quantum
system. Thus, following the idea used for the latter, we study the possibility
of creating entanglement using squeezed coherent states of the Morse potential
as an input field of a beam splitter. We measure the entanglement with the
linear entropy for two types of such states and we study the dependence with
the coherence and squeezing parameters. The new results are linked with
observations made on probability densities and uncertainty relations of those
states. The dynamical evolution of the linear entropy is also explored.
