Using a germanium-detector array for hypernuclear spectroscopy (Hyperball), we measured B(E2) of the Li hypernucleus and observed a significant shrinkage of the 6Li core induced by a -particle. In this way, nuclear properties can be drastically changed by introducing a -particle, which can be investigated by high-resolution hypernuclear spectroscopy. In the future neutron-rich hypernuclei will also be studied, where interesting modifications of nuclear structure by a -particle are expected.
