Dipole responses in γ−soft 124-134Xe in the spectroscopic energy region

This study aimed to systematically investigate the low-lying dipole states of even-even 124-134Xe isotopes using the quasi-particle random phase approximation (QRPA) method. Where in all the studied xenon isotopes, electric and magnetic dipole responses were clearly predicted. The calculations predict mainly a scissors mode, while the strength of weakly deformed 132, 134Xe was small compared to moderately deformed 124-130Xe isotopes, where electric dipole excitations make their own contributions as well. The obtained results are consistent with the available experimental data. Since it was not possible to experimentally determine the parity of dipole states here trougth comparison our results with experiment, we investigated the role of electric and magnetic dipole excitations in forming the spectrum. After comparing the obtained results with the experimentally derived ones, the natures of several observed spin- and parity-unknown excitations were determined.
