Nucleus resonance frequency of the hydrogen atom = 42.58mhz
« on: March 17, 2009, 11:10:49 am »
Hi,

Here is another study of me:


The Larmor precession frequency is the rate of precession of a spin packet under the influence of a magnetic field. The frequency of an RF signal, which will cause a change in the nucleus spin energy level, is given by the Larmor equation. The frequency is determined by the gyro magnetic ratio of atoms and the strength of the magnetic field. The gyromagnetic ratio is different for each nucleus of different atoms.
The stronger the magnetic field, the higher the precessional frequency. If an RF pulse at the Larmor frequency is applied to the nucleus of an atom, the protons will alter their alignment from the direction of the main magnetic field to the direction opposite the main magnetic field. As the proton tries to realign with the main magnetic field, it will emit energy at the Larmor frequency. By varying the magnetic field across the body with a magnetic field gradient, the corresponding variation of the Larmor frequency can be used to encode the position. For protons (hydrogen nuclei), the Larmor frequency is 42.58 MHz/Tesla.


The Larmor equation is important because it is the frequency at which the nucleus will absorb energy. The absorption of that energy will cause the proton to alter its alignment and ranges from 1-100 MHz in MRI. The equation states that the frequency of precession of the nuclear magnetic moment is directly proportional to the product of the magnetic field strength (B0) and the gyromagnetic ratio (g). This is stated mathematically as w= gB0.


Nucleus
The core or center part of an atom, which contains protons having a positive charge and neutrons having no electrical charge, except in the common isotope of hydrogen, where the nucleus is a single proton.

 
Nuclei    Unpaired Protons    Unpaired Neutrons    Net Spin     (MHz/T)       
1H    1    0    1/2    42.58       
2H    1    1    1    6.54    

Spin
What is spin? Spin is a fundamental property of nature like electrical charge or mass. Spin comes in multiples of 1/2 and can be + or -. Protons, electrons, and neutrons possess spin. Individual unpaired electrons, protons, and neutrons each possesses a spin of 1/2.

Properties of Spin
When placed in a magnetic field of strength B, a particle with a net spin can absorb a photon, of frequency V . The frequency depends on the gyromagnetic ratio, of the particle.  For hydrogen, = 42.58 MHz / T.          V=Y.B

Ps. If any of you have an idea on how to build a test setup, please let me know.

That formula is variable to the strenght of the field in tesla .

This resonance claim of 42.8 khz is nothing but jibberish .

Its about this dual resonance , the atoms and the electric circuit , superimposed .

Tom Bearden is right I believe .

Yes, it is variable depending on the magnetic field.
But i would not call this jibberisch.
This is proven technology in MRI. Hospital technology.

How would it be possible to create such a magfield? How would we get 1 Tesla or 1.5 tesla?
How much is needed to kick the nucleas ass?

there is the NMR of earth.. NMR is used also in millitary applications for those who know.. last post im out-
