Nuclear Energy Levels and Mass of Nitrogen-17

Abstract

Energy levels and the atomic mass defect of the nucleus ${\mathrm{N}}^{17}$ have been determined by measuring the kinetic energies of proton groups produced in the reaction ${\mathrm{B}}^{11}({\mathrm{Li}}^7, p){\mathrm{N}}^{17}$ on bombardment of isotopically separated ${\mathrm{B}}^{11}$ targets with 2-Mev ${\mathrm{Li}}^7$ ions.
