We derive the equations to calculate the reduced-width amplitudes (RWAs) of unequal-sized clusters and deformed clusters without any approximation. These equations, named the Laplace expansion method, are applicable to nuclear models that use Gaussian wave packets. The advantage of the method is demonstrated by numerical calculations of the O-16 + alpha and Mg-24 + alpha RWAs in Ne-20 and Si-28.
