A nucleus A, with a finite de-broglie
wavelength $\lambda $A, undergoes spontaneous fission
into two nuclei B and C of equal mass. B flies
in the same direction as that of A, while C flies
in the opposite direction with a velocity equal
to half of that of B. The de-Broglie wavelengths
$\lambda $B and $\lambda $C of B and C are respectively :
$\lambda $A, 2$\lambda $A
2$\lambda $A, $\lambda $A
$\lambda $A, $\lambda $A/2
$\lambda $A/2, $\lambda $A
