SUMMARY:Universal Rainbow Channeling Potential
DESCRIPTION:The problem of an accurate ion-solid interaction potential is one of the basic problems in description of the ion-solid interaction [1]. It has been shown how one can construct the universal rainbow channeling proton-crystal interaction potential [2]. It has been done by modifying the Moliere’s interaction potential applying the crystal rainbow theory [3\, 4]. This potential merges the ZBL potential\, for the small impact parameters\, and the Molière’s potential\, with the Thomas-Fermi radius\, for the large impact parameters. The accuracy of the obtain interaction potential should be investigated in a series of high resolution transmission channeling experiments for different proton-crystal combinations. Further\, application of the presented rainbow morphological method for 5 keV protons transmitted through a graphene [5] and generally through 2D materials has been disused.\n[1] M. Nastasi\, J. W.
