Abstract
The low-energy nuclear structure of the neutron-rich Cl isotopes is studied via in-beam -ray spectroscopy following the fragmentation of K projectiles on a Be target at intermediate beam energies. coincidence information was used to construct level schemes for these neutron-rich nuclei. For the nucleus Cl, the lifetime of the first excited state at 130 keV was extracted via -ray line shape analysis, yielding an strength an order of magnitude greater than that predicted by theory. The experimental data is compared to the results of large-scale shell-model calculations with effective interactions in the - model space.
