First Results on γ-Ray Spectroscopy in the Second Minimum of ²³⁸U and ²⁴⁰Pu

RADIOACTIVITY ^238mU(SF) [from ²³⁸U(d, pn), E=20 MeV]; ^240mPu(SF) [from ²³⁸U(α, 2n), E=25 MeV]; measured prefission γ-spectra, γ(delayed-fission)-coin. ²³⁸U, ²⁴⁰Pu deduced second minimum vibrational band deexcitation transitions. Crystal ball.
