Photodissociation of alkali–halides is studied using a hybrid close‐coupling and multichannel quantum defect theory approach. A novel class of interferometry that arises from the coherent interference of alternative pathways to bond breaking is identified. Interferometric resonances that live for hundreds of picoseconds are analyzed in the spirit of channel interaction. Interfering patterns that form in the interaction zone due to collision of nuclear wavepackets are revealed. © 2000 John Wiley & Sons, Inc. Int J Quant Chem 80: 958–965, 2000
