Creating a source for cold, magnetically-trapped bromine atoms

Thesis

This thesis demonstrates the feasibility of producing the first cold source of halogen atoms, using Br atoms as the focus. Br atoms are produced by photodissociation of Br2, and detected by (2+1) REMPI and time-of-flight measurements. Ground- and excited-state Br fragments are formed with a recoil velocity directed along the molecular beam axis. The excess energy from the dissociation laser provides the backscattered Br fragments with sufficient recoil velocity to match and cancel out the aver...
