Energy Levels of Calcium Isotopes.Ca40(d, p)Ca41Reaction

Abstract

The ${\mathrm{Ca}}^{40}(d, p){\mathrm{Ca}}^{41}$ reaction was investigated with the MIT-ONR electrostatic generator, a 180-degree magnetic spectrograph, and a magnetic broad-range spectrograph. Bombarding energies from 2.5 to 7.0 Mev were used; targets were made of natural calcium; and the reaction angle was 90 degrees. The $Q$ value for the transition to the ground state of ${\mathrm{Ca}}^{41}$ is 6.140±0.009 Mev. Twenty-five excited states of ${\mathrm{Ca}}^{41}$ were found in the region of excitation from 1.947 to 4.194 Mev.
