Inverse Geomentry

Inverse Geometry gives to one the possibility to obtain the data for different reactions with the same combination of incident particle and target nucleus, for example

d + ³He = p + ⁴He

and

³He + d = p + ⁴He

in one request and for energy recalculated from LAB-system to SCI-system

E_SCI = - (M_a + M_b) + ((M_a + M_b)² + 2E_LABM_b)^1/2.
