Nature Chem.


Intrabeam Scattering

First results from our new MURI machine for ultracold collisions have just been published in JPC Letters. This apparatus is now performing novel high resolution merged beam scattering of vibrationally excited molecules.


Our new instrument coupling near-IR cw-cavity ring-down spectroscopy with our pulsed uniform supersonic flows is now coming on line.
