Size, of nucleus

The present calculation takes into account all these effects for Coulomb-Coulomb and Coulomb-Breit interaction and omits effects l)-3) for Breit-Breit interaction. On the other hand we, in contrast to [2], carry out all the calculations in the point nucleus approximation. The corrections to the finite size of nucleus for the bound energy as well as the corrections to the finite size of nucleus for electron interaction are considered separately (see Table 1). 

Notice The correction to the finite size of nucleus is included in corrections RMBPT, SE, VP and others but is not included in QED-INT. A correction NS in Table 1 is derived as the difference between corrections NS for 2pi/2 and 2si/o states of U91+. 

For calculations of the first order corrections for uranium ions we took into account the effect of finite size of nucleus. To perform it the Dirac equation for the states lsi/2, 2.s- /2, 2pi/2 was solved with the potential that corresponds to a Fermi distribution for the nuclear charge... 

The induction time, x, is a function of subcooling and reflects the time necessary for a critical size of nucleus to be developed in the liquid. The induction time is also dependent on the size at which nuclei are detectable and the growth rate at this early stage. Despite this limitation in measurement methods, induction times are often considered to be inversely proportional to nucleation rate (4)... 

The corrections to finite size of nucleus for the energy of configuration (151/2) in the second order, according [27], yields 0.07eV. For the difference of the energies of the configurations (l5i/2) 25i/2 (l5i/2) 2pi/2 this correction must... 

The structure of such metallopolymers can be regulated by varying the ratio of sizes of block-copolymer (general molecular weight, composition) and micelle parameters (size of nucleus/cover, form, polydispersion), and this enables us to use block-copolymers as nanoreactors or templates. The ratio between the molecular weights of the first (polar) and the second (hydrocarbon) components Mi and M2) is important to provide steric stabilization M = nM2 (where n is the number of the second component chains). As a rule, M is 10 -10 andM2 = 10 -10. ... 

Note that far from the stability region the separation energy of the outermost nucleons is small. In some cases this may lead to a drastic increase of the size of nucleus the external nucleon may occupy a distant lying orbit. For example, such proton halo exists in B, one-neutron halos in Be and and two-neutron halos in He and Li. The radii of these nuclei are extremely large, comparable with that of Ca. See Suzuki et al. (2003).

Expressions for critical sizes of nucleus can be obtained by zeroing the first derivative of A4> with respect to the dimensions of the nucleus.
