Abstract

A search for an isomeric state in the neutron-rich nucleus 19C is reported. The existence of an isomer in the nucleus is predicted by shell model calculations which also predicts the ground-state of the nucleus to be 1/2+. An isomeric transition is however not observed in the present investigation. An estimation of upper limit of isomer ratio in the beam is discussed. Furthermore, the non-observation of an isomer includes the possibility of 19C having a different ground state spin. The 17C and 17B nuclei were also investigated for delayed gamma transitions but do not exhibit any isomeric transition.
