In the early studies of (1984Se15, 1993Wa07) using 13C(π+-), the levels observed in the excitation spectrum appeared as broad groups with excitation energies around Ex=3, 4.5, 6 and 8.7 MeV. In the later work of (2007GuZW), using 16O(3He,6He), more structures are observed revealing a collection of narrower states. Finally, in the seminal work of (2021Ch45), analysis of the decay mechanism further resolved the groups observed by (2007GuZW) into narrower states that dominantly proton decay to different 12N states.
