Projectile:
Section for projectile nucleus. The projectile will start at \(z < 0\) and fly in positive \(z\)-direction, at \(x \ge 0\).
Target:
Section for target nucleus. The target will start at \(z > 0\) and fly in negative \(z\)-direction, at \(x \le 0\).

(double, optional):To configure a fixed target heavy-ion collision with deformed nuclei, whose spherical deformation is explicitly declared, it can be done according to the following example. For explanatory (and not physics) reasons, the projectile's Woods Saxon distribution is initialized automatically and it's spherical deformation manually, while the target nucleus is configured just the opposite.
