Evolution of quadrupole collectivity in N=80 isotones toward the Z=64 subshell gap: The $B(E2;2_{1}^{+} \rightarrow 0_{1}^{+})$ value of $^{142}$Sm

It was shown that the evolution of the $B(E2;2_{1}^{+} \rightarrow 0_{1}^{+})$ values in $N$ = 80 isotones from Te to Nd is affected by the underlying subshell structure. This manifests itself in the observation of the local suppression of the $B(E2)$ value at $Z$ = 58 with respect to the neighboring nuclei $^{136}$Ba and $^{140}$Nd. [...]

Magnetism of an Excited Self-Conjugate Nucleus: Precise Measurement of the g Factor of the 21+ State in Mg24
/ Kusoglu, A ; Stuchbery, A E ; Georgiev, G ; Brown, B A ; Goasduff, A ; Atanasova, L ; Balabanski, D L ; Bostan, M ; Danchev, M ; Detistov, P et al.
A precise measurement of the g factor of the first-excited state in the self-conjugate (N=Z) nucleus Mg24 is performed by a new time-differential recoil-in-vacuum method based on the hyperfine field of hydrogenlike ions. Theory predicts that the g factors of such states, in which protons and neutrons occupy the same orbits, should depart from 0.5 by a few percent due to configuration mixing and meson-exchange effects.

Res. ; Leuven U.) ; Ionescu-Bujor, M (Bucharest, IFIN-HH) ; Iordachescu, A (Bucharest, IFIN-HH) ; Bazzacco, D (INFN, Padua ; Padua U.) ; Brandolini, F (INFN, Padua ; Padua U.) ; Bucurescu, D (Bucharest, IFIN-HH) ; Chmel, S (Bonn U., HISKP) ; Danchev, M (Sofiya U.) ; De Poli, M (INFN, Legnaro) ; Georgiev, G (CSNSM, Orsay) et al.
The spectroscopic quadrupole moment of the T(1/2) = 9.4(5) ns isomer in (193)Pb at an excitation energy E(ex) = (2585 + x) keV is measured by the time-differential perturbed angular distribution method as vertical bar Q(s)vertical bar = 2.6(3) e b. Spin and parity I(pi) = 27/2(-) are assigned to it based on angular distribution measurements. [...]
