Coulomb excitation of pear-shaped nuclei / Butler, Peter (Liverpool U.) ; Gaffney, Liam (Liverpool U. ; CERN) ; Spagnoletti, Pietro (West Scotland U.) ; Konki, Joonas (CERN) ; Scheck, Marcus (West Scotland U.) ; Smith, John (West Scotland U.) ; Abrahams, Kenzo (Western Cape U.) ; Bowry, Michael (TRIUMF) ; Cederkäll, Joakim (Lund U.) ; Chupp, Timothy (Michigan U.) et al.
There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipole moments of atoms, which would indicate CP violation and hence probe physics beyond the Standard Model of particle physics. [...]

The nature of quadrupole and octupole collectivity in 222222Rn was investigated by determining the electric-quadrupole (E2) and octupole (E3) matrix elements using subbarrier, multistep Coulomb excitation. The radioactive 222222Rn beam, accelerated to 4.23 MeV/u, was provided by the HIE-ISOLDE facility at CERN. [...]

Fine structure in the α decay of 2219022190Th, populating excited states in 2178821788Ra, was studied using αγ-coincidence spectroscopy. Two α-decay branches from 221221Th have been newly observed, with Eα(keV)[bα(%)]=7951(8)[0.14(3)]Eα(keV)[bα(%)]=7951(8)[0.14(3)] and 8247(3)[1.51(12)]8247(3)[1.51(12)], together with three previously known branches.

The dipole strength of the nuclide 6666Zn was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of energies of 7.5 and 13.4 MeV at the γELBE facility as well as using quasimonoenergetic and linearly polarized photon beams of 30 energies within the range of 4.3 to 9.9 MeV at the HIγS facility. A total of 128 J=1 states were identified, among them 9 with 1++ and 86 with 1 assignments. [...]

A projectile Coulomb-excitation experiment was performed at the radioactive-ion beam facility HIE-ISOLDE at CERN to obtain E2 and M1 transition matrix elements of 140Nd using the multistep Coulomb-excitation code GOSIA. The absolute M1 strengths, B(M1;2+22+1)=0.033(8)μ2N,B(M1;2+32+1)=0.26+0.110.10μ2N, and B(M1;2+42+1)<0.04μ2N, identify the 2+3 state as the main fragment of the one-quadrupole-phonon proton-neutron mixed-symmetry state of 140Nd.

Evolution of quadrupole collectivity in N=80 isotones toward the Z=64 subshell gap: The B(E2;2+10+1) value of 142Sm / Stegmann, R (Darmstadt, Tech. Hochsch.) ; Bauer, C (Darmstadt, Tech. Hochsch.) ; Rainovski, G (Sofiya U.) ; Pietralla, N (Darmstadt, Tech. Hochsch.) ; Stahl, C (Darmstadt, Tech. Hochsch.) ; Bönig, S (Darmstadt, Tech. Hochsch.) ; Ilieva, S (Darmstadt, Tech.

It was shown that the evolution of the B(E2;2+10+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 136Ba and 140Nd. [...]
