Level Structure ofNi64

Fundamentals In Nuclear Physics

“…If we assume that the mean potential energy is harmonic, the energy levels are E n = (n + 3/2)hω n = n x + n y + n z = 0, 1, 2, 3 . The allowed values of l for each n are shown in the second line of The magic numbers corresponding to all shells filled below the maximum n, as shown on the fourth line of Table 2.2, would then be 2,8,20,40,70,112 and 168 in disagreement with observation (2.37). .…”

“…The parity is the sign by which the total constituent wavefunction changes when the spatial coordinates of all nucleons change sign. The spectrum on the top right is a schematic of the energy spectrum of final-state protons (at fixed scattering angle of 60 deg) for an initial proton energy of 11 MeV (adapted from [20]). Fortunately, identical nucleons tends to pair with another nucleon of the opposite angular momentum so that in the ground state, the quantum numbers are determined by unpaired protons or neutrons.…”

The spin of the 2,198 keV level in74Ge and multipole mixing ratios of gamma transitions in the decay of74As

“…Data on these levels have also been taken in (n, 7) [7], (p, p') [8], (t, p) [9] and Coulomb excitation studies [10][11][12]. From the results of these experiments the level scheme of 74Ge populated by the decay of 74As shown in Fig.…”
