Kinematics

To generate a kinematics plot, first create a TKinematics object. A constructor is available that uses char arrays to call TNucleus objects. To use it, the syntax is as follows:

TKinematics(beam_energy,beam,target,ejectile,recoil)

As an example,

 TKinematics *mykin = new TKinematics(520.0,"Sr95","p","p","Sr95")

Next, if we want to generate the E vs Lab Theta we would use the function Evslab. The syntax for that is:

Evslab(start_angle,stop_angle,angle_step_size,particle)

The particle field needs a bit of explanation, it is an integer corresponding to what one you are interested in, from right to left in the TKinematics constructor. As an example:

 mykin->Evslab(1,89,1,2)

Where the 2 means we are interested in the proton. This returns a TSpline3 object, which can be drawn or stored using the typical ROOT commands.
