Description

Run  TGenPhaseSpace for the reaction  d+He8 -> H7+He3  1) with the projectile energy in the Lab ref. frame of 400 MeV per nucleon 

   Draw distributions of the He3 momentum absolue value, theta ,  Cos(theata),  phi and corellations of the values  

2) Boost the reaction to the CM ref. frame and run the TGenPhaseSpace there. Draw the same distribution as above but in CM.  Cos(theta) and phi distributions should be uniform, absolute value of the momentum should be peak-like, no corellations should be observed in CM.

3) boost the results of 2) to the Lab ref frame and compare with the results of 1)  they should be the same.

#3 Updated by Ilyas Satyshev about 5 years ago

1) In this case, we used TGenPhaseSpace classically. Distributions were got.

#4 Updated by Ilyas Satyshev about 5 years ago

2) The reaction was Boosted to the CM ref. frame and the TGenPhaseSpace is run there. cos(thetaCM) and phiCM distributions are uniformly as we were waiting. The absolute value of the momentum is peak-like. The correlations question needs to be discussed.

#5 Updated by Ilyas Satyshev about 5 years ago

3) The results from the previous case were boosted from CM to Lab ref. frame and distributions and correlations for all of them are presented in the corresponding pictures.

#6 Updated by Ilyas Satyshev about 5 years ago


4. Classically use of the TGenPhaseSpace class gives uniform distribution for the 3He energy. Pictures energy.png and kinEnergy.png show corresponding distributions.
