Energy Levels ofCa43

The ${\mathrm{Ca}}^{42}(d, p){\mathrm{Ca}}^{43}$ and ${\mathrm{Ca}}^{43}(p, p^{\prime }){\mathrm{Ca}}^{43}$ reactions were investigated with the MIT-ONR electrostatic generator and a magnetic broad-range spectrograph. Bombarding energies from 5.0 to 7.4 Mev were used; targets were made of magnetically separated isotopes. The $Q$-value of the ${\mathrm{Ca}}^{42}(d, p){\mathrm{Ca}}^{43}$ ground-state transition is 5.711±0.010 Mev. Thirty excited states of ${\mathrm{Ca}}^{43}$ in the region below 3.43 Mev are well established.
