Abstract:
Four rotational bands (Kπ = 0+, 2+, 0-, 3-) in the
low-energy region of 24Mg are investigated with an extended
deformation model which treats quadrupole (Y2) and octupole
(Y3) deformations of the intrinsic one-body field and
single-particle modes in it. The Kπ = 0± bands are
described as the inversion doublet with the lowest configuration
in the deformed field and the Kπ = 2+ and 3- bands
are constituted by their respective 1p-1h excited configurations.
The Y2 + Y3-deformation which has been proposed through energy
variation is well-substantiated by the electromagnetic properties
pertaining to the four bands. The present model successfully
reproduces the enhanced E3-transition data between the
Kπ= 0± bands. The enhancement of these transitions is
basically that of the Q3-moment of the intrinsic state which
is caused by a collective correlation, i.e., the Y3-type of
the deformation in the intrinsic state. The model also gives a
good representation of the observed rotational character, i.e.,
the strong intra-band E2-transitions as well as the J(J+1)
rule in the energy spectrum both in the Kπ= 0± bands
and in the Kπ= 2+, 3- bands with the 1p-1h configurations.
