Evidence for an i13/2 neutron band in133Sm

  • Short Note

Zeitschrift für Physik A Atomic Nuclei

Abstract

A rotational band of nine γ-rays has been observed in133Sm. The moment of inertia of the band indicates that it has a higher deformation than expected for states in nuclei in this region. The properties are such that it can be interpreted as being due to the odd neutron occupying the ν i2/13 nn intruder orbital. This is the first evidence for the occupation of this orbital in nuclei with neutron number N<73.
