2136.60 | In 1969Wi16, the level scheme was built with the 405-keV γ and the 217-keV γ depopulating the same level. In 2001Ge07, however, the γ-rays in coincidence with the 405 γ are not in coincidence with the 217 γ. As a consequence, the adopted level scheme is built assuming they originate from 2 different levels, very close in energy.
