//to find kinetic energy lost by neutron
// GIVEN:
//initial kinetic energy of neutron
K1i = 5.0//in MeV
//mass of neuron mn
mn = 1//considering it as unity as other masses are given with reference to mn
//mass of neucleus of lead
mPb = 206*mn
//mass of neucleus of carbon
mC = 12*mn
//mass of neucleus of hydrogen
mH = mn
// SOLUTION:
//As collision is elastic collision
//using conservation of energy principle
//collision with neucleus of lead
//final kinetic energy of neutron
K1f = K1i*((mn-mPb)/(mn+mPb))^2//in MeV
//kinetic energy lost by neutron
K_lostl = K1i-K1f//in MeV
//collision with neucleus of carbon
//final kinetic energy of neutron
K1f_C = K1i*((mn-mC)/(mn+mC))^2//in MeV
//kinetic energy lost by neutron
K_lostC = K1i-K1f_C//in MeV
//collision with neucleus of lead
//final kinetic energy of neutron
K1f_H = K1i*((mn-mH)/(mn+mH))^2//in MeV
//kinetic energy lost by neutron
K_lostH = K1i-K1f_H//in MeV
