b decays of on-line mass-separated neutron-rich 118Ag and 120Ag isotopes have been studied by using b-g and g-g coincidence spectroscopy. Extended decay schemes to the 118,120Cd daughter nuclei have been constructed. The three-phonon quintuplet in 118Cd is completed by including a new level at 2023.0 keV, which is tentatively assigned the spin and parity of 24 1 . The intruder band in 118Cd is proposed up to the 41 level at 2322.4 keV. The measured b-decay half-life for the high-spin isomer of 120Ag is 0.4060.03 s. Candidates for the three-phonon states, as well as the lowest members of the intruder band in 120Cd, are also presented. These data support the coexistence of quadrupole anharmonic vibration and proton particle-hole intruder excitations in 118,120Cd.

Precision Mass Measurements on Neutron-Rich Rare-Earth Isotopes at JYFLTRAP : Reduced Neutron Pairing and Implications for r-Process Calculations

Vilén, Markus; Kelly, J. M.; Kankainen, Anu; Brodeur, M.; Aprahamian, A.; Canete, Laetitia; Eronen, Tommi; Jokinen, Ari; Kuta, T.; Moore, Iain; Mumpower, M. R.; Nesterenko, Dmitrii; Penttilä, Heikki; Pohjalainen, Ilkka; Porter, W. S.; Rinta-Antila, Sami; Surman, R.; Voss, Annika; Äystö, Juha (American Physical Society, 2018)

The rare-earth peak in the r-process abundance pattern depends sensitively on both the astrophysical conditions and subtle changes in nuclear structure in the region. This work takes an important step towards elucidating ...
Evolution of deformation in neutron-rich Ba isotopes up to A=150

The occurrence of octupolar shapes in the Ba isotopic chain was recently established experimentally up to N = 90 . To further extend the systematics, the evolution of shapes in the most neutron-rich members of the ...
Collectivity of neutron-rich magnesium isotopes investigated by projected shell model calculations

Dong, G X; Wang, Xiaobao; Liu, H.L.; Xu, F.R. (American Physical Society, 2013)

The abnormally large collectivity of neutron-rich magnesium isotopes in the “island of inversion” has not been well understood. It has been commented that the unexpectedly large deformations observed in the magnesium isotopes ...
Trap-assisted studies of odd, neutron-rich isotopes from Tc to Pd

Kurpeta, J.; Jokinen, Ari; Penttilä, Heikki; Płochocki, A.; Rissanen, Juho; Urban, Waldemar T.; Äystö, Juha (Springer, 2014)

We review the present and future of trap-assisted structure studies of odd, neutron-rich Tc, Ru, Rh and Pd isotopes at the limits of present experimental techniques. These nuclei of refractory elements are produced in ...

Rotational structures have been measured using the Jurogam II and GAMMASPHERE arrays at low spin following the 155Gd(α,2n)157Dy and 148Nd(12C,5n)155Dy reactions at 25 and 65 MeV, respectively. We report high-K bands, which ...
