A rotational band has been unambiguously observed in an odd-proton transfermium nucleus
for the first time. An in-beam γ-ray spectroscopic study of 251Md has been performed using the
γ-ray array JUROGAM combined with the gas-filled separator RITU and the focal plane device
GREAT. The experimental results, compared to Hartree-Fock-Bogolyubov calculations, lead to the
interpretation that the rotational band is built on the [521]1/2− Nilsson state. |
