Delayed Mu formation in Solid Nitrogen

• Phases of solid nitrogen (s-N₂)

Surprising results and hints: Mu formation depends on temperature!

• Early Russian results in s-N₂
• Early TRIUMF results: Dia & Mu components in s-¹⁴N₂
• Slow & Fast diamagnetic components in s-¹⁴N₂

The explanation becomes obvious:

• T-dependence of Mu formation & electron mobility in s-N₂

• Electric field dependence of Mu formation in s-N₂

• Magnetic field dependence of Mu signal amplitude in s-N₂

What is the Dia component, anyway?

• Molecular ion N₂ µ⁺ confirmed by quadrupolar ALCR in s-N₂
