Abstract

The neutron-rich $^{106}$ Mo nucleus has been studied by prompt γ-ray spectroscopy following the spontaneous fission of $^{248}$ Cm. The characteristics of the rotational band built on a state at 1435 keV identifies the band head as the best candidate for a harmonic double-phonon $K^{π} {= 4}^{+}$ γ-vibrational state observed so far.
