Nuclear wave function in function of for the proton state, obtained by diagonalizing the self energy in the exact continuum used above. The first eigenvalue at -23.97 MeV (solid red line) is compared by the corresponding harmonic oscillator state multiplied by the square root of the spectroscopic factor (dashed red line), the second eigenvalue at -2.85 MeV (solid blue line) is similarly compared with harmonic oscillator state (dashed blue line).
I am setting up and using the public github repository after many years. I decided to start releasing some old projects publicly, since seems apparent I will never have time to write anymore papers, nor to polish the code.
Eventually, at least for these little “didactic” subprojects, I will start to do little explanatory videos, or blogposts, instead of articles just to save times and make the process more fluid.
There are several aspects of the paper of Norman Cook and Andrea Rossi that scream “amateurish”: from layout to typos (hoping they’re so), from historical concepts to bibliography, I’m not certainly the only one to have noted them.
But is the scientific thesis to be flawed, even without considering the disputed history of E-cat and LENR and possible prejudices one can have on the author and its reasons.
The comparative half life ft is useful to compare the strength of the and electron-capture processes over different nuclei. -decay half lives can span several orders of magnitude, from fraction of seconds to thousands of time the age of the universe. Some of these striking differences are due to relatively trivial energetic conditions, but the more interesting from a nuclear structure point of view are due to the wavefunction superposition and the angular momentum coupling.
The three Borromean rings. There are some properties of few-body systems that are “Universal”, so shared between all few-body systems that feel an attractive interaction (with certain boundary properties for defining eventual spin-orbit and isospin).
An example of this behavior are the Efimov states of three-body systems: when an interaction loosely bound two bodies, the three-body system have a precise spectrum of excitation. This spectrum is observed in three nucleons systems like Helium-3 and Triton, since the two-body system, the deuteron, is loosely bound (for nuclear scales).
Today I learned something more about sterile neutrinos, and the latest advancement to the quest of finding them
