a question about tunneling phenomena

Recommended Posts

the attempt frequency of an [math]\alpha[/math] particle to escape the nucleus is the number of times per seconds it collides with the nuclear barrier. Estimate this collision frequency in the tunneling model forthe [math]\alpha[/math] decay of thorium assuming the [math]\alpha[/math] behaves like a true particle inside the nucleus with total energy equal to the observed kinetic energy of decay. the daughter nucleus for this case (radium) has z=88 and a radşus of 9.00 fm. take the overall nuclear barrier 30.0 MeV measured from the bottom of the nuclearwell to the top of the coulomb barrier.

 

my mate asked that problem yo me but i couldnt solve it can u help me ?
