Abstract
Spin and parity assignment in 152gd investigating octupole structures
The high-spin states of the nucleus ls2cd have been populated via the ls2sm (cr, 4n)
152Gd fusion-evaporation reaction at abeam energy of 45MeV. The emitted y rays
were observed with the AFRODITE spectrometer afiay. The previously known decay
scheme of 1s2cd
was extended. Directional Correlation from Oriented states of nuclei
(DCO) and linear polarization measurements were performed in order to assign spins
and parities in the 1s2cd decay scheme. An alternative interpretation of the first
excited Kn: 0* band, previously considered to be a B-vibration is discussed.
