Question

Calculate the capture rate where Cn=10, Nt=10^10cm^-3, n=10^20 and fF (Et)=0.4.

(a) 6*10^30

(b) 5*10^30

(c) 36*10^30

(d) 1.66*10^29

This question was posed to me during a job interview.

Answer 1

Correct answer is (a) 6*10^30

To explain I would say: Rcn=Cn*N_t*(1-fF (Et))*n

Substituting the values,

Rcn=6*10^30.
