The observation of vibrating pear-shapes in radon nuclei
/ Butler, P.A. (Liverpool U.) ; Gaffney, L.P. (Liverpool U. ; CERN) ; Spagnoletti, P. (West Scotland U.) ; Konki, J. (CERN) ; Scheck, M. (West Scotland U.) ; Smith, J.F. (West Scotland U.) ; Abrahams, K. (Western Cape U.) ; Bowry, M. (TRIUMF) ; Cederkäll, J. (Lund U.) ; Chupp, T. (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. [...]

Determination of the B(E3, 0(+) -> 3(-))-excitation strength in octupole-correlated nuclei near A approx 224 by the means of Coulomb excitation at REX-ISOLDE
/ Scheck, M ; Gaffney, L P ; Butler, P A ; Hayes, A B ; Wenander, F (CERN) ; Albers, M ; Bastin, B ; Bauer, C ; Blazhev, A ; Bönig, S et al.
The IS475 collaboration conducted Coulomb-excitation experiments with postaccelerated radioactive (220)Rn and (224)Ra beams at the REX-ISOLDE facility. The beam particles (E(beam) ≈ 2.83 MeV/u) were Coulomb excited using (60)Ni, (114)Cd, and (120)Sn scattering targets. [...]

A magnetically shielded room with ultra low residual field and gradient
/ Altarev, I. (Munich, Tech. U.) ; Babcock, E. (ZAT, Julich) ; Beck, D. (Illinois U., Urbana (main)) ; Burghoff, M. (Berlin, Phys. Tech. Bund.) ; Chesnevskaya, S. (Munich, Tech. U.) ; Chupp, T.

A versatile and portable magnetically shielded room with a field of (700 \pm 200) pT within a central volume of 1m x 1m x 1m and a field gradient less than 300 pT/m is described. This performance represents more than a hundred-fold improvement of the state of the art for a two-layer magnetic shield and provides an environment suitable for a next generation of precision experiments in fundamental physics at low energies; in particular, searches for electric dipole moments of fundamental systems and tests of Lorentz-invariance based on spin-precession experiments.

Studies of pear-shaped nuclei using accelerated radioactive beams
/ Gaffney, L P (Liverpool U.) ; Butler, P A (Liverpool U.) ; Scheck, M (Liverpool U. ; Darmstadt, Tech. Hochsch.) ; Hayes, A B (Rochester U.) ; Wenander, F (CERN) ; Albers, M (Cologne U.) ; Bastin, B (GANIL) ; Bauer, C (Darmstadt, Tech. Hochsch.) ; Blazhev, A (Cologne U.) ; Bonig, S (Darmstadt, Tech. Hochsch.) et al.
There is strong circumstantial evidence that certain heavy, unstable atomic nuclei are ‘octupole deformed’, that is, distorted into a pear shape. This contrasts with the more prevalent rugby-ball shape of nuclei with reflection-symmetric, quadrupole deformations. [...]
