Odd-Even Staggering of Nuclear Masses: Pairing or Shape Effect?
Odd-Even Staggering of Nuclear Masses: Pairing or Shape Effect?
The odd-even staggering of nuclear masses was recognized in the early days of nuclear physics. Recently, a similar effect was discovered in other finite fermion systems, such as ultrasmall metallic grains and metal clusters. It is believed that the staggering in nuclei and grains is primarily due to pairing correlations …
