Question: An-particlewith mass m = 4.0026 u and Energy E = 4.0 MeV tunnels through a wall with height U 0 = 32.4 MeV and width

An-particlewith mass m = 4.0026 u and Energy E = 4.0 MeV tunnels through a wall with height U₀ = 32.4 MeV and width l = 19 fm. Inside the uranium nucleus potential energy of the -particleis zero and width of the nucleus is r = 16 fm.

Calculate the probability of tunneling for the -particle and the speed and with the help of these results estimate the lifetime for uranium.
