Signatures of criticality in the evolution of the nuclear ground-state shapes across the N× Z
plane are discussed. Attention is paid to specific data indicating sudden structural changes …

The rapid shape change in Zr isotopes near neutron number N= 60 is identified to be
caused by type II shell evolution associated with massive proton excitations to its 0 g 9/2 …

The structure of even-even neutron-rich Ru, Mo, Zr, and Sr nuclei in the A≈ 100 mass
region is studied within the interacting boson model (IBM) with microscopic input from the …

This article is devoted to a review of decay properties of excited 0+ states in regions of the
nuclear chart well known for shape coexistence phenomena. Even-even isotopes around …

Background: The mass region with A≈ 100 and Z≈ 40 is known to experience a sudden
onset of deformation. The presence of the subshell closure Z= 40 makes it feasible to create …

Background: Even-even isotopes of Mo (Z= 42) and Ru (Z= 44) are nuclei close to the
subshell closure at Z= 40, where shape coexistence plays a significant role. As a result, their …

The lifetimes of the first excited 2+, 4+, and 6+ states in Zr 98 were measured with the recoil-
distance Doppler shift method in an experiment performed at GANIL. Excited states in Zr 98 …

Rapid shape changes are observed for neutron-rich nuclei with A around 100. In particular,
a sudden onset of ground-state deformation is observed in the Zr and Sr isotopic chains at …

The first fast-timing measurements from nuclides produced via the in-flight fission
mechanism are reported. The lifetimes of the first 2+ states in 104,106 Zr nuclei have been …

Atomic masses of Sr 95–100, Zr 98–105, and Mo 102–110 have been measured with a
precision of 10 keV employing a Penning trap setup at the IGISOL facility. Masses of Zr 104 …
