We have investigated the role of momentum dependent s-wave and higher partialwave strong interactions to determine the ground state properties and thecolumn densities in the Bose-Einstein condensate (BEC) for large scatteringlength (a) such that ka >>1 even for small values of momentum where themomentum p=(h/2pi)k and k is the wave number. Since the scattering length islarge we have included the first correction (Lee-Huang-Yang correction) bothfor the k-dependent (s-wave + higher partial wave) interactions andk-independent contact interactions (s-wave). We have derived thetime-independent equations from the corresponding energy functionals and foundthat the ground state properties and the column densities differ significantlyfor these two types of interactions even for moderate values of scatteringlength (a = 3000 a_0) in BEC of cylindrically trapped 85Rb atoms at 100 nK. Theeffect of higher partial wave (d-wave) increases with increase in a and it is >20% for peak density at a= 8700 a_0 which can be experimentally detected.Dependence of column density on particle number density has been studied.Column densities have been compared with experimental results.
