Uk. Pal et al., Measurement of the energy dependence of level density over a wide range inneighbouring odd and even-even nuclei, J PHYS G-NU, 25(8), 1999, pp. 1671-1679
The energy dependence of the nuclear level density in As-69 and Ge-70 has b
een extracted from the first-step evaporation proton spectra in the reactio
ns C-12 + Ni-58 and C-12 + Co-59 at E-beam = 36-60 MeV. Their comparison pr
ovides information on the excitation energy dependence of the pairing and s
hell effect over a wide range of similar to 5-24 MeV.
