Multiple shape coexistence near Sn118: First 03+ lifetime measurement
F. Wu, C. R. Ding, C. Andreoiu +17
The intruder bands in Sn isotopes, built on the 2p-2h excitation across the proton shell gap, are well-known examples of shape coexistence near the neutron mid-shell regio…
Lifetime of the state of Te
H. Mayr, T. Stetz, V. Werner +22
The evolution of the collectivity of tellurium isotopes from mid-shell towards is currently based mainly on properties of the first excited states. To extend structura…
Evidence for shape coexistence in Sn from the first lifetime measurement
F. Wu, C. Andreoiu, V. Karayonchev +14
The lifetime of the state in Sn was measured for the first time applying the fast-timing technique following thermal neutron capture. The mean lifetime of $Ï= 50(7…
Intruder structures in Si and Al
J. Williams, G. Hackman, K. Starosta +31
We have studied Si and Al using C(Ne,2p) and C(Ne,p) fusion-evaporation reactions. In both cases, we observed significant population o…
Revised value in the semi-magic nucleus Pb
C. M. Nickel, V. Werner, G. Rainovski +25
The lifetime of the state of Pb was measured in the Pb(O, O)Pb two-neutron transfer reaction by -ray spectroscopy employing the re…
First measurement of 87Rb(α, xn) cross sections at weak r-process energies in supernova ν-driven ejecta to investigate elemental abundances in low-metallicity stars
C. Fougères, M. L. Avila, A. Psaltis +18
Observed abundances of Z ~ 40 elements in metal-poor stars vary from star to star, indicating that the rapid and slow neutron capture processes may not contribute alone to the synt…
