  Laser cooling unlocks metal tracer

  Atom trap trace analysis has emerged as a powerful technique for detecting trace radioisotopes of noble gases. The successful application of the method to a calcium isotope now opens the possibility of extension to other metal isotopes.

  Atom-trap trace analysis of ⁴¹Ca/Ca down to the 10^–17 level

  The calcium isotope ⁴¹Ca is a promising candidate to complement dating methods relying on radiocarbon. Small levels of ⁴¹Ca can be measured with atom-trap trace analysis, which brings the use of ⁴¹Ca a step closer to applications.

  Precision mass measurement of lightweight self-conjugate nucleus ⁸⁰Zr

  High-precision mass measurements of exotic zirconium nuclei are reported, and reveal a double-shell closure for the deformed nucleus ⁸⁰Zr, which is more strongly bound than previously thought.
