Abstract
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.
