Abstract

We report the results of numerical modeling of the coherent laser multi-pulse technique, proposed in our earlier papers to measure the population of the metastable states of antiprotonic helium and to control the decay kinetics in the adjacent transition chains. It is demonstrated that a sequence of properly chosen (pi) -pulses may result in a sequence of annihilation spikes whose amplitudes are nearly proportional to the populations of individual metastable states. The limitations related to the pulse duration and delay are studied as well as the role of the lifetime of the short-lived final state.
