The SAGE Spectrometer

The first experimental campaign of SAGE was performed in April and May 2010.

Two experiments were performed studying shape coexistence in the mid-shell nuclei mercury and radon.

• Shape coexistence in ^182-188Hg

  (P.A. Butler, P. Rahkila and P. Van Duppen)

  M. Scheck et al., Phys. Rev. C 83, 037303 (2011)

• Exploring shape coexistence in ^202,204Rn

  (D.G. Jenkins, A.P. Robinson and P. Rahkila)

 

The second campaign took place from January to March 2012 and concentrated mainly on studies of superheavy nuclei.

• Spectroscopy of the odd-proton ^249,251Md

  (Ch. Theisen)

• Simultaneous conversion-electron and gamma-ray spectroscopy using SAGE; an in-beam study of ²⁵³No

  (R.-D. Herzberg and P. Papadakis)

• Complete spectroscopy of the transfermium nucleus ²⁵⁵Lr

  (M. Sandzelius, K. Hauschild and A. Lopez-Martens)

• Probing E0 transitions in ¹⁸⁸Pb using the SAGE spectrometer

  (J. Pakarinen and P. Papadakis)

• Exploring nuclear shapes in the transitional region of N~90: Coulomb excitation of ^152,154Sm to study E0 transitions with SAGE

  (P. Davies)

 

The third experimental campaign was successfully completed between June and November 2013.

• Simultaneous in-beam gamma-ray and conversion electron spectroscopy of ¹⁹⁴Po employing the SAGE spectrometer

  (J. Pakarinen and P. Rahkila)

• Probing the E0 transitions in ¹⁸⁶Pb using the SAGE spectrometer

  (J. Pakarinen, P. Papadakis and D.G. Jenkins)

• Characterisation of a new structure in octupole-deformed ²²²Th using gamma-ray and conversion electron spectroscopy

  (J. Smith and P.T. Greenlees)

• Study of the structure of high-K states in ²⁵⁴No using the SAGE spectrometer

  (P. Papadakis, P.T. Greenlees and R.-D. Herzberg)

• Spectroscopy of the odd-proton nucleus ²⁴⁹Md and feasibility study for ²⁴³Es

  (Ch. Theisen, P.T. Greenlees and R.-D. Herzberg)

• Shape coexistence in Odd-Au isotopes: In-beam Gamma-ray and Conversion Electron Spectroscopy

  (M. Venhart and D.T. Joss)
