Abstract: Random sequential adsorption of ellipsoids and spherocylinders is studied in order to find the shape that maximises the mean saturated packing fraction. It was found that for ellipsoids the maximum is reached for axes ratio of 0.7:1:1.6 and is equal to 0.43772±0.00051. For spherocylinders, the highest density was measured for length-to-width ratio of 1.8 and is equal to 0.42515±0.00030. The study of kinetics of packing growth shows that a packing built of more anisotropic objects grows slower. The microstructural properties of the obtained packings are analysed in terms of two-point density and order correlation functions.
