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.
Attach to the issue the macros and the pictures.

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

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.

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