Abstract: | Using a germanium-detector array for hypernuclear γ spectroscopy (Hyperball), we measured B(E2) of the 7 ΛLi hypernucleus and observed a significant shrinkage of the 6Li core induced by a Λ-particle. In this way, nuclear properties can be drastically changed by introducing a Λ-particle, which can be investigated by high-resolution hypernuclear γ spectroscopy. In the future neutron-rich hypernuclei will also be studied, where interesting modifications of nuclear structure by a Λ-particle are expected. Received: 1 May 2001 / Accepted: 4 December 2001 |
