We have observed the energy shifts and intensity ratios of the K x rays of titanium and copper excited by bombarding foils of these materials with fission fragments from the spontaneous fission of Cf252. A lithium-drifted-silicon detector was employed to make the measurements. For both metals studied, larger shifts in the x-ray energies were observed than were recorded for nickel by Watson and Li in their investigation using only the light fission fragments as projectiles. In addition, the KβKα intensity ratio for titanium, after correcting for K-edge absorption in the foil, was found to be very small. We interpret this last result as being due to very high stripping of the M shell of the recoiling titanium atom in collisions with other titanium atoms.
