get the number of bursts of light exceeding a given size per particle passing through Uses the scintillating solution as target and detector He is now working on this. A new aspect recently occurred to me: If albedo consists of electrons (and μ mesons less so!) then no bursts of comparable size would be produced (less than a radiation length, say) Result obtained = ( (j sub ([protons, alpha, Hear?))(sigma sub C) (epsilon {efficiency} ) ) Thus if (sigma sub C) is obtained by some other method, epsilon is obtained, then ((j sub total) - (j sub ([protons, alpha, etc?])) should equal (j sub albedo).
