A numerical simulation is used to predict the interaction between the earth’s bow shock and lithium to be released in the solar wind during the Active Magnetospheric Particle Tracer Explorers program in 1984. Based on the simulation results for a release near the subsolar point, it is recommended that a favorable release condition is when the garden‐hose angle of the interplanetary magnetic field exceeds about 60 to 70° so that the transmission of Li + ions through the bow shock is optimized. The model also predicts that the Li + is “shock‐drift” accelerated at the bow shock. The energy gain of Li + ions is on the average less for the transmitted particles (below a factor of about 4) than for the reflected particles (below a factor of about 16).
