The space-charge spreading of the beam in the ion-extraction region of a liquid-metal ion source is evaluated by calculating the ion trajectories. The rate of increase is the emission angle for the modified "Taylor cone" anode is expressed by a universal curve given by a function of (dI/dΩ)_0M^<1/2>/(V_<AC>/α)^<3/2>. Here, (dI/dΩ)_0 is the angular ion intensity on the anode surface, M is the atomic mass of a singly-charged ion, V_<AC> is the difference in potential between the anode and the cathode, and α is a shape factor for the anode.
