carbon cycle barrier

[AntonioLao]

Self-catalytic fusion cycle is also known as the carbon-nitrogen cycle of thermonuclear reactions. This type of reaction was theorized by Hans Bethe in 1938 which was instrumental for his award of 1967 Nobel Prize in Physics http://nobelprize.org/physics/laureates/1967/ . The reactions are as follows: a carbon-12 (12C) nucleus captures a hydrogen nucleus (1H, a proton) to form a nucleus of nitrogen-13 (13N); a gamma ray (g) is emitted in the process. The nitrogen-13 nucleus emits a positive electron (positron, e+) and becomes carbon-13 (13C). This nucleus captures another proton, becomes nitrogen-14 (14N), and emits another gamma ray. The nitrogen-14 captures a proton to form oxygen-15 (15O); the resulting nucleus ejects a positron as above and is thereby transformed to nitrogen-15 (15N). Eventually, the nitrogen-15 nucleus captures a fast-moving proton and breaks down into a carbon-12 nucleus plus a helium nucleus (alpha particle) of mass 4 (4He). In symbols:
For these to be effective the barrier of high temperature beyond a few millions degrees must be surmounted.

Why is thiswork not followed up then Antonio? Ifthis was achieved then,what are they doing now!
kind regards michael.

Why is this work not followed up

It is an engineering obstacle of reaching the temperature threshold of about ten millions degrees and a fusion density 12 times the density of lead.
