Excited States ofCu64andCu66

Abstract

The ${\mathrm{Cu}}^{63}(d, p){\mathrm{Cu}}^{64}$ and ${\mathrm{Cu}}^{65}(d, p){\mathrm{Cu}}^{66}$ reactions have been investigated through studies of the proton groups arising from the deuteron bombardment of thin targets of isotopically enriched copper. The incident deuteron beam, with energies ranging from 6.00 to 6.55 Mev, was obtained from an electrostatic accelerator, and the protons were analyzed with a high-resolution magnetic spectrograph. In the region of excitation up to 3.80 Mev, sixty-five excited states in ${\mathrm{Cu}}^{64}$ and fifty-five in ${\mathrm{Cu}}^{66}$ have been measured. The $Q$ values for the transitions to the ground states of ${\mathrm{Cu}}^{64}$ and ${\mathrm{Cu}}^{66}$ are 5.691±0.008 Mev and 4.832±0.008 Mev, respectively.
