Nilsson diagram

Nilsson diagram for protons with tc = 0.067 and m 0.53 BCS model Fermi level for Y with Ap 0.69 MeV is indicated by dots. 

Fig. 3 Nilsson diagram for odd neutrons close to N = 82, calculated with the parameter set k = 0X)5 and p. = 020 valid in the spherical limit 176]. The Fermi levels for N - 83,85 and 87 indicate a successive filling of the fj neutron shell. In the right part, experimental data on magnetic dipole moments and spectroscopic quadrupole moments of I = 712 ground states in N = 83,85 and 87 nuclei (Ba [39] Ce, Nd and Sm [1] Gd, Dy and Er [48]) are compared with the results from the particle-rotor calculations, assuming deformations of e = 0.10 and 0.15.

Fig. 7 Nilsson diagram for odd protons, including sublevels of the shell model states gy,2, d 2 and The Fermi levels of jl, Cs andgfii, g Fr are shown to be located at the lower parts of the gj,2, dg and h sublevels, respectively. The theoretical results on the spectroscopic quadrupole moments as a function of d ormation are given to the right. The potential parameters used are k=0.066, p = 0575for I and Cs, and k = 0.060, p = 0.630for Bi and Fr.

The observed quadrupole moment of Co is 0.40 bam. (a) What is the deformation value ff (b) What spin value is etqtected from the Nilsson diagram ... 

Nilsson diagram. Single-particle energies (Cs.p. in /iwo 41 MeV units) as functions of the deformation parameter 8. (Based on Nilsson 1955). The calculations were extended by Bengtsson and Ragnarsson (1985) also to other regions, separately for protons and neutrons and different 2, 4 deformations, see Firestone et al. (1996)...
