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 ?

If the alpha has the observed decay energy, how fast is it moving? How many time will it hit the barrier, given the nuclear size?

it is the what problem asks us.

it simply depends upon frequency of collision and according to uncertainty principle there is no constant no. of collisions, it is all probability,

and the movement of alpha particle also cannot exactly be predicted
