Methods for cooling thick spallation targets (emphasis is on targets for an ISL facility) to uniform temperatures are discussed along with methods for testing targets in a manner that does not require an accelerator facility or result in induced radi

Excitation functions for compound-nucleus and transfer reactions have been measured with 48Ca ions on 208Pb targets. A comparison is made with the 40Ar-on-208Pb reaction to explain the observed anomalous behavior of the transfer reactions and a surpr

We have investigated the chloride complexation of element 104 and compared it to that of the actinides and Hf. The 65-s α-emitting isotope 261104 was produced via the bombardment of 248Cm with 18O ions, and the recoil products were transported to a

The mechanical limits of thin metal foils were studied under conditions which simulated heavy-ion beam experiments. The properties of He and N 2 as cooling gases were evaluated; helium was found to be superior to nitrogen in all cases. The most durab

Starting with polonium in 1898, alpha spectrometry has played a decisive role in the discovery of new, heavy elements. For even-even nuclei, alpha spectra have proven simple to interpret and exhibit systematic trends that allow extrapolation to unkno

Schemes that could be used for detection of superheavy elements (SHE) are briefly discussed first. The question of producing SHE in other than complete fusion reactions (e.g., in deep inelastic reactions) is addressed at greater length. Production cr

A novel ion source based on an electron-beam-generated plasma is described. It features high efficiency and high temperature operation (∼ 3000 K). It does not incorporate magnetic fields and delivers beam of high quality suitable for mass spectrome
