A multiple contact adhesion model has been derived to explain the charge observed on silica dust. This model has good agreement with the observed adhesion of microspheres and microballoons. From theoretical arguments, it appeared feasible that surface acoustic waves could be used to overcome the electrostatic adhesion between a particle and surface, and be used to move the particle along the surface in a controllable fashion. In an inverted geometry, evidence for resonance in the hollow microballoons was found. Two distinct modes were observed. These were the breathing mode and the Lamb wave mode associated with resonance of the walls. The measured Lamb wave velocity was 6.15 x 10/sup 5/ cm/sec.

Absolute disintegration rates of specific radioactive products induced by neutron irradition of a sample are determined by spectrometric analysis of gamma-ray emissions. Nuclide identification and quantification is carried out by a complex computer code GAMANAL (described elsewhere). The output of GAMANAL is processed by NADAC, a computer code that converts the data on observed distintegration rates to data on the elemental composition of the original sample. Computations by NADAC are on an absolute basis in that stored nuclear parameters are used rather than the difference between the observed disintegration rate and the rate obtained by concurrent irradiation of elemental standards. The NADAC code provides for the computation of complex cases including those involving interrupted irradiations, parent and daughter decay situations where the daughter may also be produced independently, nuclides with very short half-lives compared to counting interval, and those involving interference by competing neutron-induced reactions. The NADAC output consists of a printed report, which summarizes analytical results, and a card-image file, which can be used as input to another computer code MERGE. The purpose of MERGE is to combine the results of multiple analyses and produce a single final answer, based on all available information, for each element found.

Laser plasma experiments at the Lawrence Livermore Laboratory have progressed very rapidly and have achieved new milestones in both the implosion and DT gain in laser fusion targets. New diagnostic methods were also developed for determining the state of the compressed fuel and the plasma processes which are occurring in the absorption and scattering of the laser light incident on the laser fusion pellets. A review of the program is given. (MOW)
