Single-particle spectra

Trimborn et al. (2000) describe a four-week field campaign to characterise an aerosol in a particular area, where the LAMPAS 2 instrument was continuously analysing the size and composition of individual particles in five size ranges between 0.2 pm and 1.5 pm. Some 10,000 single particle spectra were recorded during the measuring period, and one example of these is shown in Figure 3.13. 

We present the resulting calculations of single-particle spectra for four electrons (2 of each spin direction) on a linear ring of four sites. The singleparticle single-band Hamiltonian describing the non-interacting system is... 

Figures 1 shows, for U = 10.0, the single-particle spectra for four electrons on a ring of four sites (half-filled band) obtained in the ordinary version of HF...

Figure 1 Single-particle spectra for a ring with four sites with U = 10.0. The solid line is the spectrum calculated from the restricted HF while the dashed line is the spectrum obtained with the 2HF, and the dotted line is the exact spectrum.

A study of the superheavy region with self-consistent mean field models (employing mean field and Skyrme-Hartree-Fock approaches) yields different results for predicted regions of stability. O Figure 19.16 displays the single-particle spectra for neutrons and protons (Bender et al. 2001) for Sn, the superheavy nucleus 126, and the hyperheavy nucleus 164. They exhibit a significant difference in the nature of the shells of doubly magic tin (where proton and...

Shell-Correction and Averaging of Single-Particle Spectra for the Modified Nilsson Potential... 

Having obtained the single-particle spectra, the empirical shell correction (in the spirit of Strutinsky s method [38]), is determined from Eq. (14). 

This level scheme should be compared to the calculated single particle spectra [76] shown in Fig. 32. The ground state in all cases is 1. The lowering in...
