*DISTANCES, *LUNAR surface
Abstract

We report on a determination of the Earth-Moon distance, performed by students of an Italian high school, based on measurements of the time delay of the "echo" in the radio communications between NASA mission control in Houston and the Apollo astronauts on the lunar surface. By using open-source audio-editing software, the distance can be determined with a∼0.1% accuracy, allowing us to observe the effect of the eccentricity of the orbit of the Moon.

Nucleon deuteron scattering, hyperspherical harmonics method
Abstract

The structure of N—d low-energy scattering states is described using the hyperspherical harmonics method with realistic Hamiltonian models, consisting of two- and three-nucleon interactions. Both coordinate and momentum space two-nucleon potential models are considered. Results for the zero-energy N—d scattering lengths and for the p—d phase shift and mixing angle parameters at center-of-mass energy of 2 MeV are presented and discussed.
