A proton and an alpha particle of identical energy encounter potential barriers of identical height and width. For which is the probability of transmission greatest and why?

thanks

Energy is the same - ostensibly, that means - kinetic energy.

But what is different. How about mass.

Think about the particle wavefunction - http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/barr.html#c1
