Abstract
The structure of 246Fm has been investigated using in‐beam γ‐ray spectroscopy. The experiment was performed at the University of Jyväskylä using JUROGAM 2 coupled to RITU and GREAT. The 246Fm nuclei were produced using a 186 MeV beam of 40Ar impinging on a target of 208Pb. JUROGAM 2 was fully instrumented with TNT2D digital acquisition cards. The use of digital acquisition cards and a rotating target allowed for unprecedented beam intensities up to 71 particle‐nanoamperes for prompt γ‐ray spectroscopy. With all these major advances for spectroscopy a rotational band is observed for the first time in 246Fm and discussed here. © 2011 American Institute of Physics
