Description
Available experimental data on excited levels of the 148Ce nucleus are analyzed. With the aid of model concepts and systematics that cover neighboring nuclei, the spectrum of 148Ce is supplemented with a Kπ = 2- rotational band that has a bandhead at 1368.98 keV, which extends up to the 16- state at 3897.9 keV, and which is new. Three states at E = 1422.85, 1786.57, and 2198.6 keV of spin-parity 5+, 7+, and 9+, respectively, are included in the gamma-vibrational band featuring the known 2+ and 3+ levels at 989.90 and 1116.63 keV, respectively. A significant difference in the behavior of the moments of inertia in positive-and negative-parity bands is highlighted.
