Decay of Alpha Particle Through Quantum Tunneling

[OhMyGod]

Homework Statement

By using the graph attached,
Why high energy alpha particles are emitted by alpha-emitters of short wavelength?

Homework Equations

Transmission Coefficient Equation : T=exp(-2kd)

The Attempt at a Solution

Ain't really sure. Can't really figure out why is the graph shaped like that in the first place.
Anyone wants to give it a shot into explaining what accounts for this the shape of the graph first?



Many thanks in advance :D

i reckon the energy of the nucleons is very low in the well, ie the nucleons are most stable there (due to conditions given by strong nuclear force), the rapid peak indicates that outside this radius, the energetic stability is very low, hence peak energy value, this subsides with increasing distance inversely with distance - arising due to coulomb force.

so am i within the 10^-15m or have i missed the point, i am humble i can handle it.
