Using a germanium-detector array for hypernuclear $\gamma$ spectroscopy (Hyperball), we measured B(E2) of the $^7_\Lambda$Li hypernucleus and observed a significant shrinkage of the 6Li core induced by a $\Lambda$-particle. In this way, nuclear properties can be drastically changed by introducing a $\Lambda$-particle, which can be investigated by high-resolution hypernuclear $\gamma$ spectroscopy. In the future neutron-rich hypernuclei will also be studied, where interesting modifications of nuclear structure by a $\Lambda$-particle are expected.
