Here we analyse the isotopes of carbon..

The novelty is that starting up from the carbon the nuclear tables give the magnetic moments on excited isotopes. With the exception of 5B10, the nuclear tables do no give information for the excited isotopes of 2He, 3Li, 4Be and 5B.

### Excited light nuclei with Z < 8

When a light nucleus with Z < 8 is excited its nucleons can change their position or their spin in the structure of the isotope as shown in the Figure

#### Magnetic moment of excited 5B10

##### 5B10 with no excitation

The calculation was exhibited in the PART TWO, and we repeat it here:

### Calculation on magnetic moments of carbon isotopes

The structure of 6C12 is also shown in the page 231 of the book QRT. Its structure is similar to that of 4Be8, but the flux n(o) is reinforced by the addition of more 2 protons and 2 neutrons.

#### 6C10

The cause why 6C10 is no stable is similar to that of the isotope 4Be8, where the two deuterons repel each other, and they penetrate within the central 2He4, broking its structure.

But note that 4Be8 has half-life extremelly short, 6,7×10?17 s , while 6C10 has half-life 19,3 seconds, in spite of 6C10 has two free protons captured by the flux n(o) !

The longer half-life of 6C10 is because there is a repulsion between the proton p-2 and the deuteron D-1 (and also between p-1 and D-2), and such repulsion disturb the process of penetration of the proton within the structure of the central 2He4.

#### Stable 6C12

##### The mystery of excited 6C12

The excited 6C12 has a mystery: it has nuclear spin i=2 and null nuclear magnetic moment. It’ impossible to conciliate these two nuclear properties from the current nuclear models of the Standard Nuclear Physics.

The mystery is solved by considering the foundations that rule the behavior of nuclei proposed in the new nuclear model of Quantum Ring Theory.

#### Stable 6C13

In the PART TWO of this series of five articles the isotope 6C13 was used as calipers for the calculation of the Multiplication Factor MfE= 3,94, as follows:

1- The starting point of calculation was an imaginary neutron in the isotope 5B10, occupying the place of one of the protons

2- From the magnetic moment of the imaginary neutron, the magnetic moment of the proton was calculated

3- A Multiplication Factor MfE was calcuted for the isotope 5B10

4- The MfE obtained was applied for the calculaton of the magnetic moment of 6he 6C13, so that to achieve +0,7024 (the experimental value).

5- If the value +0,7024 should not be achieved, a new attempt was done with another initial value of the imaginary neutron.

6- The value +0,702 was obtained when MfE =3,94

#### 6C14

Its structure is similar to that of the 10Be: the excess neutron is captured by the two sides of the central 2He4.

Look at to their long half-life:

10Be: 1,30x106years

14C: 5,70x103years
