Zusammenfassung:
In the annihilation of a positron with a bound atomic electron, the virtual
gamma photon created may excite the atomic nucleus. We put forward this effect
as a spectroscopic tool for an energy-selective excitation of nuclear
transitions. This scheme can efficiently populate nuclear levels of arbitrary
multipolarities in the MeV regime, including monopole transitions and giant
resonances. In certain cases, it may have a higher cross sections than the
conventionally used Coulomb excitation.
