  • Coulomb excitation of Rn 222 
    Butler, P.A.; Gaffney, L.P.; Abrahams, K.; Bowry, M.; Cederkäll, J.; Chupp, T.; De Angelis, Angelis; De Witte, Witte; Garrett, P.E.; Goldkuhle, A.; Henrich, C.; Illana, A.; Johnston, K.; Joss, D.T.; Keatings, J.M.; Kelly, N.A.; Komorowska, M.; Konki, J.; Kröll, T.; Lozano, M.; Singh, B. S. Nara; O'Donnell, D.; Ojala, J.; Page, R.D.; Pedersen, Line Gaard; Raison, C.; Reiter, P.; Rodriguez, J.A.; Rosiak, D.; Rothe, S.; Scheck, M.; Seidlitz, M.; Shneidman, T.M.; Siebeck, B.; Sinclair, J.; Smith, J.F.; Stryjczyk, M.; Van Duppen, Duppen; Viñals, S.; Virtanen, V.; Wrzosek-Lipska, K.; Warr, N.; Zielińska, M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The nature of quadrupole and octupole collectivity in 222Rn was investigated by determining the electric-quadrupole (E2) and octupole (E3) matrix elements using subbarrier, multistep Coulomb excitation. The radioactive ...
  • Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive 222Ra and 228Ra Beams 
    Butler, Peter A.; Gaffney, LP; Spagnoletti, P.; Abrahams, K.; Bowry, M.; Cederkall, Joakim; De Angelis, G.; De Witte, H.; Garrett, P.E.; Goldkuhle, A.; Henrich, C.; Illana, A.; Johnston, K.; Joss, D.T.; Keatings, J.M.; Kelly, N.A.; Komorowska, M.; Konki, J.; Kröll, Th; Lozano, M.; Nara Singh, B.S.; O'Donnell, D.; Ojala, J.; Page, R.D.; Pedersen, Line Gaard; Raison, C.; Reiter, Peter; Rodriguez, J.A.; Rosiak, D.; Rothe, S.; Scheck, Marcus; Seidlitz, M.; Shneidman, T.M.; Siebeck, B.; Sinclair, J.; Smith, J. F.; Stryjczyk, M.; Van Duppen, P; Vinals, S.; Virtanen, V.; Warr, N.; Wrzosek-Lipska, Katarzyna; Zielinska, Magdalena (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    There is sparse direct experimental evidence that atomic nuclei can exhibit stable “pear” shapes arising from strong octupole correlations. In order to investigate the nature of octupole collectivity in radium isotopes, ...
  • The observation of vibrating pear-shapes in radon nuclei 
    Butler, P.A.; Gaffney, LP; Spagnoletti, P.; Konki, J.; Scheck, M.; Smith, J.F.; Abrahams, K.; Bowry, M.; Cederkall, J.; Chupp, T.; De Angelis, G.; De Witte, H.; Garrett, P.E.; Goldkuhle, A.; Henrich, C.; Illana, A.; Johnston, K.; Joss, D.T.; Keatings, J.M.; Kelly, N.A.; Komorowska, M.; Kröll, T.; Lozano, M.; Nara Singh, B.S.; O'Donnell, D.; Ojala, J.; Page, R.D.; Pedersen, Line Gaard; Raison, C.; Reiter, P; Rodriguez, J.A.; Rosiak, D.; Rothe, S.; Shneidman, T.M.; Siebeck, B.; Seidlitz, M.; Sinclair, J.; Stryjczyk, M.; Van Duppen, P; Vinals, S.; Virtanen, V.; Warr, N.; Wrzosek-Lipska, K; Zielinska, M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    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 ...
