  The ground state property of Yukawa Bose fluid confined in a radial harmonic
trap is studied. The calculation was carried out using the density functional
theory formalism within the Kohn-Sham scheme. The excess-correlation energy for
this inhomogeneous fluid is approximated via the local density approximation. A
comparison is also made with the Gross-Piteavskii model. We found that the
system of bosons interacting in terms of Yukawa potential in a harmonic trap is
energetically favorable compared to the ones interacting via contact delta
potential.
