To explore sub-atomic structures accelerators are microscopes to see sub-atomic structures.

Particles (p,e) gain lots of momentum by speeding them up to  ~ c (speed of ligh), then particle wavelength is very short:

Probug particles shooting high energy particles at a fixed target or to each other provides collisions.

THE OBSERVATION OF PARTICLES ON EMILSION PLATE

 

Pion which has a high energy and high velocity spreads after hit to a nükleus in the

film and it is spreaded in a three dimentional position.

            However a pion particle which has less energy and velocity goes on to lose its energy and after that it becomes spoiled. After this it throws a neutrino particle and at the result of this a muon which has a higher energy found out.

            Muon loses it velocity and energy and than it throws a neutrino. At the result of this an

electron exists

Muon and neutrino go on to their direction in opposite ways. However neutrino has not got any heap and iyonize value so it can not be seen with eyes. The energy of neutrino  can be calculate with using the energy and momentum of pion and muon.

TO CALCULATE THE MOMENTUM OF MUON

        

The becoming spoiled and effects of the reaction of pion which is in silver bromude film can be seen with a research  with stereo optic microscope.

With using the layer and horizontal values of microscope, the length of muon which is in the film can be calculate as micron value.

We take the value of momentum which is opposite to lenght in lenght-momentum graphic.

TO CALCULATE THE ENERGY OF NEURINO

 

E² = p ² . c   ²  + m ² .c⁴

 

^{E = Energy}

^{P = Momentum}

^{M= Heap}

^{C= light’s speed}

 

^MUON

 

E² = 2,9² MeV/c . c² + 105,6²  MeV/c². c⁴

 

E² =  8,41 . 0.99+ 11151,36. 0.98

 

E² =   8.32 + 10928,3

 

E² = 10936,653    E= 104,5

 

 

PION

 

     P = m.V    (m pion’s relativity  heap)

 

   m=         ^m 

         1- V²  / c²   =  141,8

 

   E² = 141,8²  MeV/c .c²  + 139² MeV/c² .c⁴

 

   E² =  19906 +18934,5 = 38840;5   E= 197 MeV

 

NEUTRINO’S ENERGY

 

   197 MeV – 104,5 MeV  =  92,5 MeV
