Nuclear Energy Levels inMn55

Abstract

Inelastically scattered protons from manganese targets bombarded with protons from an electrostatic accelerator have been studied with the high-resolution magnetic spectrograph. Forty-three excited states in ${\mathrm{Mn}}^{55}$ have been established in the region between the ground state and 4.0 Mev. The first five of these levels are at 0.127, 0.983, 1.289, 1.527, and 1.884 Mev.
