The first measurement of polarized x-rays from a laser-produced plasma is reported. The degree of polarization is related to the net anisotropy of the hot-electron velocity distribution.

A measurement of the distribution of the number of neutrons per fission of ${\mathrm{Pu}}^{240}$ yielded the following probabilities, ${P}_{m}$, for 0,1,2, etc. neutrons: ${P}_{0}=0.062$, ${P}_{1}=0.198$, ${P}_{2}=0.374$, ${P}_{3}=0.228$, ${P}_{4}=0.

Neutron emission from laser-produced plasmas is shown, experimentally, to be adequately explained by electron heating and electrostatic ion acceleration. The absence of anomalous ion-heating mechanisms is not proved, but these mechanisms, if they exi

In CO2 laser interaction with matter most of the absorbed energy is initially channeled into a hot electron distribution. In many cases, resonance absorption is thought to be the dominant mechanism producing this distribution. Stimulated scattering m

The x‐ray bremsstrahlung from 4 to 50 keV emitted by laser‐produced plasmas has been measured using a Bragg crystal spectrometer. Direct spectral information was obtained in contrast to earlier filter spectroscopy. Measurements were made with foc

Data on the emission of energetic ions produced in laser–matter interactions have been analyzed for a wide variety of laser wavelengths, energies, and pulse lengths. Strong correlation has been found between the bulk energy per AMU for fast ions me
