A new experiment to measure differential cross sections as a function of the bombarding energy and scattering angle for the 16O + 28Si system in order to discriminate regular and chaotic regimes, was performed using the particle spectrometer CHICO co

A compact ion source has been designed for use in the production of amorphous carbon thin films with diamond-like properties. This filament-discharge ion source works very efficiently at a low input electrical power. The design, which is simple and r

Lifetime measurements of the 5−1, 4−1, and 3−2 levels in 144Nd, coupled with measurements of the M1/E2 mixing of the 4−1→3−1 and 3−2→3−1 transitions, show that the transition strengths from these levels are in good agreement with th

Sources of 54 Mn, 55 Ni, and 144 Pm were placed at the center of the Gammasphere array and searches were made for the astrophysically interesting β + decay modes of these isotopes. The results of these searches are presented and the implications for

The results of a 1.94 kg · y pilot search for solar axions with an ultralow background Ge detector are reviewed. The detection method is based on Bragg-coherent Primakoff conversion of axions into photons when the momentum vectors of the axion and p

Results are reported of an experimental search for the unique, rapidly varying temporal pattern of solar axions coherently converting into photons via the Primakoff effect in a single crystal germanium detector. This conversion is predicted when axio

A global systematic analysis relating the asymptotic enhancement of sub-barrier fusion cross sections with the product of the coupling strength times the value of the Coulomb barrier is presented. It is found that all systems involving static deforma

Average angular momenta of compound nuclei were deduced from measured evaporation-residue cross sections on the basis of statistical model calculations. We have applied this method to the following systems: {sup 4}He+{sup 197}Au, {sup 16}O+{sup 147,1

The {beta} -decay half-life of {sup 54}Mn is needed to employ this isotope as a cosmic ray chronometer. We have determined the partial half-life of {sup 54}Mn for positron emission by counting a highly purified 35-{mu}Ci source of {sup 54}Mn in GAMMA

We have measured the ratio of the yields for the metastable and ground states of {sup 119}Te produced in the fusion-evaporation reactions {sup 110}Pd({sup 12}C,3n) and {sup 115}In({sup 7}Li,3n) by off-line observation of delayed {gamma}-ray emission.
