Abstract
A Ti:sapphire laser of focused intensity up to 2 X 10(15) W cm-2 has b een used to search for direct (correlated) electron emission in atomic uranium using the molecule UF6. The aim was first to use ion time-of- flight (TOF) spectroscopy to provide evidence of correlated emission a nd then to apply the electron-electron (EE) covariance mapping techniq ue to confirm its existence. The ion TOF spectra did not provide suffi cient encouragement to warrant proceeding with the EE coincidence expe riment but suggested an approach that might be successful.
