Odd tensor electric transitions in high-spin Sn-isomers and generalized seniority
The similar behavior of the B(E1) values of the recently observed 13− odd tensor E1 isomers and the B(E2) values of the 10+ and 15− even tensor E2 isomers in the Sn-isotopes has been understood in terms of the generalized seniority for multi-j orbits by using the quasi-spin scheme. This simple appro...

| Summary: | The similar behavior of the B(E1) values of the recently observed 13− odd tensor E1 isomers and the B(E2) values of the 10+ and 15− even tensor E2 isomers in the Sn-isotopes has been understood in terms of the generalized seniority for multi-j orbits by using the quasi-spin scheme. This simple approach proves to be quite successful in explaining the measured transition probabilities and the corresponding half-lives in the high-spin isomers of the semi-magic Sn-isotopes. Hence, we show for the first time the occurrence of seniority isomers in the 13− Sn-isomers, which decay by odd-tensor E1 transitions to the same seniority states. |
