Perpetual Atomics, QSA Global produce Am fuel for nuclear space power
U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

Classical anisotropic scattering in the laboratory is examined for a moving-target medium. Legendre expansions of the scattering probability function f(v’,v) are given in the physical region for the general case of anisotropic elastic scattering in the center-of-mass system, and the low-order expansion coefficients are listed. The effects of a moving medium are also studied in the angle transformation from center-of-mass to laboratory system, and kinematical constraints linking angles, masses, and particle and material speeds are listed.
