Abstract

I will discuss our efforts towards reaching ultra-cold temperatures with trapped molecules where molecular beams carrying both cold molecules and atoms have been decelerated and trapped in a superconducting magnetic trap. I will present our latest results demonstrating the first collisions between trapped molecules, achieved without laser cooling. In the second part of my talk I will focus on cold collisions with molecular partners that have been magnetically merged in order to reach collisions temperatures of ~10 mK. I will show that quantum phenomena dominates collisions in this cold regime and discuss the importance of molecular degrees of freedom on cold reactions. I will present our latest results where low energy collisions have been imaged using the Velocity Mapping technique allowing us to directly differentiate between quantum scattering resonances formed either by tunneling through or reflection above a potential barrier.
