** - Assumptions**

** We have defined formulas on which we shall count ****the allocated energy in time of synthesis of kernels. But for the continuation of the analysis it is necessary for us to make a number of assumptions since today it’s impossible to establish precisely which chains present in the synthesis in stars, how many kernels are participated in one act of synthesis, and under what conditions the quantity of kernels participating in one act varies.**

** Considering ****the wide scatter of stars weight, and the huge quantity of kernels participating in the synthesis in each star, it is possible to make a number of confident assumptions: **

** — Any variants, of chains of synthesis of kernels, without restriction are possible;**

** — Any quantity of kernels or ****nuclides ****participating in one act of synthesis from two j=2 and up to j=****A _{c} (A_{i})**

**is possible;**

** - It is possible that the synthesis of kernels with the mass numbers which are located at the end of the periodic table of elements and above ****A _{i}**

**> 250, but unfortunately, we are limited by the knowledge in the limits of**

**this table, therefore chains of the synthesis of kernels will be considered only by it**

**.**

** For simplification of the maintenance of the analysis we accept, that ****during the time of synthesis, the sum of protons and neutrons of kernels ****a**** and ****b**** participated in the synthesis is equal to the number of protons and the neutrons of the received kernel ****c**** (a condition**** (3.11)).**

_{ }** - A choice of a way of the analysis**

**On an example of the synthesis of two kernels or ****nuclides ****we shall consider the chosen way of the analysis.**

** In the beginning it is necessary for us to choose a chain of synthesis.**

** Let’s take for an example a chain from hydrogen with ****Z****=1 and ****A****=1 up to helium with ****Z****=2 and ****A****=5, as shown in the scheme**** № S-3.1.**

** Chain of synthesis of a kernel of helium with ****Z****=2 and A=5 from two kernels or ****nuclides **

** Participating in one act of synthesis.**

**Let’s make the table of ****nuclides ****and kernels participated in the synthesis of a kernel of helium ****He-5****.**

** Parameters of nuclides and the kernels participating in synthesis of a kernel of helium He-5.**
