Rotational behavior ofTe120,122,124

Abstract

Three consecutive Coulomb excitation experiments were performed to measure the reduced transition probabilities in 120,122,124 Te by using a 58 Ni beam. For 120 Te the collectivity was remeasured with high precision yielding a B(E2; 0 + g.s. → 2 + 1 ) value of 0.666 (20) e 2 b 2 . From the B(E2) values connecting higher-lying states, the nuclear structure of 120,122,124 Te was determined and shows a rotational behavior quite in contrast with the vibrational structure of the level schemes. The data are compared with different models.

Emerging nuclear collectivity in 124−130Te

“…The decay of the first excited state has been scaled down by a factor of 10. has not yet been reached at 124 Te. The lower mass isotopes 120,122,124 Te have known transition strengths between the 4 + 1 and 2 + 1 states [35]. The only overlapping measurements between these and present studies are for the 124 Te B(E2; 4 + 1 → 2 + 1 ) and B(E2; 2 + 2 → 2 + 1 ) values.…”

Spin-dependent evolution of collectivity in Te112

“…We notice that 112 Te shows a behavior which is similar to 118,120 Te, which are considered to be good examples of quadrupole vibrators and follow the predictions of the U (5) symmetry (vibrator limit) [23][24][25]. Hence, our results indicate that 112 Te also belongs to the same family of vibrational-like systems as 118,120 Te, which makes the 114 Te "anomaly" even more difficult to explain.…”

Re-measurement of Reduced Transition Probabilities in $^{132}$Ba

“…The matrix elements were optimized by following the procedure given in Refs. [3,20] to reproduce the experimental γ-ray yield ratios. In the present measurement, we could not detect the 2 + 2 → 0 + gs transition, however, the 2 + 2 → 2 + 1 decay was observed, as shown in Fig.…”
