Cold collisions between metastable strontium-88 atoms show high inelastic losses due to magnetic fields. This makes magnetic trapping and cooling of these atoms experimentally challenging.

Area of Science:

  • Atomic Physics
  • Quantum Mechanics
  • Cold Atom Collisions

Background:

  • Metastable strontium-88 atoms exhibit low-field seeking behavior in magnetic fields.
  • Understanding cold atom collisions is crucial for quantum technologies.

Purpose of the Study:

  • To investigate elastic and inelastic cold collisions of metastable 88Sr atoms.
  • To determine the feasibility of magnetic trapping and evaporative cooling for 88Sr and 40Ca atoms.

Main Methods:

  • Multichannel-scattering calculation.
  • Analysis of elastic and inelastic collision rates.
  • Consideration of anisotropic long-range interactions and magnetic fields.

Main Results:

  • Strong anisotropic interactions lead to significant coupling among partial waves.

  • Nonadiabatic transitions cause high rates of inelastic losses.
  • Inelastic collision rates become dominant over elastic rates at low temperatures (approx. 1 microK).

    • Conclusions:

    • Magnetic trapping and evaporative cooling of 88Sr and 40Ca atoms in low-field seeking states are likely to be experimentally difficult.
    • High inelastic losses pose a significant challenge for sympathetic cooling experiments.
