Which phenomenon limits total kinetic energy release during alpha decay?

A)Conservation of momentum
B)Heisenberg uncertainty principle
C)Pauli exclusion principle
D)Electromagnetic repulsion effects

💡 Explanation

Conservation of momentum dictates that the light alpha particle (Helium nucleus) must have higher velocity, but the residual daughter product will also recoil, therefore dividing the released kinetic energy rather than allocating all energy to alpha byproduct alone because total momentum must be conserved.
