We present multiple differential cross sections of ionization in a coplanar geometry obtained through a theoretical first-order model. We develop a simple monoelectronic approximation that permits the reduction of the multielectronic problem into a one active electron problem. The exchange effects are neglected since we consider asymmetric kinematical conditions. The influence of the passive electrons of the target is taken into account approximately by means of different model potentials. The initial molecular states of the liquid water are represented in a realistic way through a Wanni-er orbital formalism. We make a comparison with previous theoretical and experimental results, the latter ones corresponding to the gas phase.
