Analyses of 0.8 and 1 GeV p + ' 'Pb elastic angular distribution data have obtained neutron-proton rootmean-square radius differences (hr") which are not consistent. Therefore, the 0.8 GeV experiment was repeated using a high resolution spectrometer. The new higher precision data are consistent with the older data, apart from a 15% overall normalization difference. A second order Kerman-McManus-Thaler optical model analysis of the new data, using a model-independent neutron density, yields Ar"~= 0, 14+0.04 fm, in good agreement with the most recent result obtained (0.16+0.05 fm} from a similar analysis of the older 0.8 GeV data. In addition, the elastic angular distribution was extended to 42. 5' center of mass in order to explore the momentum transfer region from 3.5 to 5.3 fm '. Although the familiar diffraction pattern persists to 42.5', it was not possible within the framework of our application of the Kerman-McManus-Thaler optical model to fit the data even qualitatively at the larger momentum transfers. NUCLEAR REACTIONSPb{p,p), E=0.8 GeV, measured g(0); enriched target; resolution = 100 keV, 6~m = 2. 5' to 42.5 . Microscopic optical model analysis using KMT potential; deduced Ar, error analysis and comparison with other results.

We review ionizing radiation effects in Flash memories, the current dominant technology in the commercial non-volatile memory market. A comprehensive discussion of total dose and single event effects results is presented, concerning both floating gate cells and peripheral circuitry. The latest developments, including new findings on the mechanism underlying upsets due to heavy ions and destructive events, are illustrated

%'e measured the energies, widths, and cross sections of the isovector monopole and dipole resonances in various nuclei between Ca and osPb with the reactions (~-, m ). Both resonances exhaust approximately the same substantial fraction of the cross section calculated in a randomphase-approximationdistorted-wave-impulse-approximation model. The excitation energies and widths of the monopole and dipole are in good agreement with random-phase-approximation calculations and for the dipole they are also in agreement with other data. No isovector quadrupole resonance was observed, and the upper limits for the cross sections for the light elements are well below the sum rule strength for the isovector monopole and giant dipole resonance.
