The fishbone potential of composite particles simulates the Pauli effect by nonlocal terms. We determine the α − α fishbone potential by simultaneously fitting to two-α resonance energies, experimental phase shifts and three-α binding energies. We found that essentially a simple gaussian can provide a good description of two-α and three-α experimental data without invoking three-body potentials.

Abstract-The climate changes cause sea level variation which varies spatial and temporal significantly, and it is now possible to reconstruct how sea level varied globally and regionally with time. The sea level rose faster than the global mean since 1950 is now a fact, and although it is not the only reason for shoreline erosion but it has a significant effects on the processes of shoreline erosion. The wave's actions are a dominant cause of shoreline erosion, even if affected by higher sea level rise rates. The research project reported in this paper investigates the shoreline erosion in the north coast of Egypt. Also the negative effects have been studied using new method. The developed methodology depends on using a stationary control measuring points instead of measuring the water depths near the shore line as previous researchers get used to apply in their studies.Index Terms-Sea level rise, climate change, coastal erosion, north coast of Egypt.
