5.3.19.4. Discrete energy distribution

5.3.19.4.1. e-type = 8, (18)

Any energy distribution can be specified by giving data set of energy points e(i) and probabilities of the particle generation w(i) by hand. The number of the particle generation at the point is proportional to w(i), and the specified energy distribution is statistically described. For 18 case, energy is given by wave length (A).

ne : Number of energy points. Data must be given from the next line by the format (e(i),w(i),i=1,ne). The number of the particle generation at each energy point is proportional to w(i).

5.3.19.4.2. e-type = 9, (19)

The same energy distribution as in the case of e-type = 8, (18) can be specified. Unlike e-type = 8, (18), the distribution is described by giving data set of energy points e(i) and weights of the source particle w(i) by hand. The number of source particles generated in each point is the same for all energy point, but integrated values of the weight of source particles are adjusted to be proportional to w(i). The number of source particles generated in each bin can also be changed by specifying p(i). For 19 case, energy is given by wave length (A).

ne : Number of energy points. Data must be given from the next line by the format (e(i),w(i),i=1,ne). In default (p-type=0), equal number of particle is generated at each point. The number of source particles generated in each point is proportional to p(i).

p-type = 0, 1 : (D=0) generation option.

• For 0, p(i)=1 for all i is assumed without the following data.

• For 1, p(i) must be given from the next line by the format (p(i),i=1,ne).
