WebGrowth curves of F centres in KCl, KBr, KI and NaCl single crystals up to saturation are measured at room temperature by irradiation with 5-45 keV electrons The optical density at saturation was found to be proportional to En, with E the energy of incident electrons and n a parameter equal to between 135 and 169 according to the material The F-centre … Weblowing symmetric and bell-shaped density function. f(x) = 1 π[1+(x−µ)2]. The expectation of Bernoulli random variable implies that since an indicator function of a random variable is a Bernoulli random variable, its expectation equals the probability. Formally, given a set A, an indicator function of a random variable X is defined as, 1 A ...
