    Question on calculating mean range of alpha

    dr(H3)=N(air)/N(He) dr(air)/Sa 2x N(air) at 1 atm=N (He) at 2 atm. thus, dr(H3)=1/2 dr(air)/0.36. dr(air) i get from the curve.. am i correct?

    Question on calculating mean range of alpha

    thank you very much for your help Bob S... :) am i suppose to use equation from Pg 652 (eq 3.14)? because the book give us the relative atomic stopping power ratio...

    Question on calculating mean range of alpha

    thanks for your reply, Bob S. I already calculate the answers for a(1.33) ,b (0.165), and c, KE(alpha)=2.0541 MeV); KE(H3)= 2.7259 MeV. For question d, how mean length of alpha particle changes with pressure within the chamber? can i get directly from the curve Fig. 3.2?

    Question on calculating mean range of alpha

    Li6(n,a)H3 , Q = 4.78 Mev. The H3 and He4 products are oppositely directed, away from the site of the compound nucleus, and hence they form one straight track. How to calculate the mean range of the alpha particle if the atomic stopping power of helium realtive to air is given as 0.36?

    How Can We Determine Recoil Nuclei Kinetic Energy in a Nuclear Reaction?

    a nuclear reaction Q value is the difference in kinetic energy of the final particle and the initial particle. how we can determine the kinetic energy only for the recoil nuclei if the kinetic energy of other particles are not given?

    Kinetic energy of nuclear reaction

    reaction B10(n,alpha)Li7, Q=2.79Mev. the He4 and Li7 are oppositely directed away from the site of the compound nucleus and form one straight track. a) what is the initial kinetic energy (KE) of He4? b) what is the initial KE of Li7 nucleus? c) estimate the ratio of the specific ionization...
