An attempt was made to find the very neutron-rich isotope [Formula Presented] among the fragmentation of a [Formula Presented] [Formula Presented] beam. Evidence for the particle instability of [Formula Presented] was obtained. As part of the search, the production cross sections of 13 light neutron-rich nuclei with Be and Ta targets are presented and compared to previous data. A large enhancement of the production cross sections for a Ta target is shown and a clear energy dependence of the production cross sections is shown for very neutron-rich nuclei.
