TL;DR: In this paper, the first use of secondary-fragment gamma-ray emission in the determination of g-factors of excited states in fission fragments was presented, and the deduced g-factor fur the 2(+) state in Ba-146 provides substantiating evidence for a downward trend in 2(+ g-facts with increasing neutron number, in line with Interacting Boson Model predictions for the neutron-rich barium isotopes, assuming the quenching of the Z = 64 shell gap for N>88.

TL;DR: In this article, a study of the decay of low-lying excited states in fragments produced in the spontaneous fission of ${}^{252}\mathrm{Cf}$ has revealed a significant correlation between the angles of emission of the complementary fragment pairs, suggesting that either a larger role is played by the relative angular momentum of the fragments, or that the dealignment introduced by the neutron emission and statistical $\ensuremath{\gamma}$ decay to the ${2}_{1}^{+}$ state is larger in ${}€ 1€ +}$

TL;DR: In this article, a new high-spin level scheme of 149Nd has been identified, which is at variance with the one previously published, and the states have been populated in the 12C + 238U fusion-fission reaction at 90MeV bombarding energy and the emitted I³-transitions were detected using the Euroball III array.

TL;DR: In this paper, the Euroball and Eurogam arrays were used to detect γ rays emitted from spontaneously fissioning 248Cm and 252Cf fragments, and the results showed that yields of secondary fragment pairs, state lifetimes at around spin 10, and g-factors of excited states in fission fragments.
