We have studied the average charged particle density (<dNch/dη>), transverse momentum (pT) spectra, <pT> and azimuthal anisotropies of inclusive charged particles produced in Xe+Xe collisions at √sNN = 5.44 TeV using A Multiphase Transport Model (AMPT), which includes the deformation of Xe129 nucleus. Calculations have been performed with the string melting version of AMPT model and compared with the recent measurements from the ALICE experiment. The model results over predict the measured <dNch/dη> for central collisions, agree with the data for mid-central collisions and under predict the measurements for peripheral collisions. The centrality dependence of <pT> of charged particles measured in ALICE is not reproduced by the model results. The calculated elliptic flow (v2) from AMPT model overpredicts the ALICE measurements in central collisions but are consistent with the data in mid central collisions. We find that the model shows a mild centrality dependence of triangular flow and overestimates the ALICE measurements. Within the model framework, we have also studied various collision configurations of Xe nuclei such as body-body, tip-tip, side-side and random. We find a strong dependence of the above observable on the collision configurations.
