Figure 2. — The probability w of reactivation for irradiated phages T2 and T2r as a function 

 of the multiplicity of infection x, for several doses of radiation. Abscissae: values of x. Ordinates: 

 values of w. 



# values of w for r= 6 hits per particle. 



+ values of w for r= 10 hits per particle. 



O values of w for r = 20 hits per particle. 

 Solid lines: theoretical curves for y as a function of x for n = 25, and for the values of r given above.
