| 4 | 1) Let us introduce Tbound (? 100 KeV); below Tbound the correction to the |
---|
| 5 | differential cross section is negligibly small. |
---|
| 6 | 2) There also exists Tmax (= function (E)) defined by kinematics. In this case, the |
---|
| 7 | following possibilities appear: |
---|
| 8 | 3) Tmax < Tbound; usual BBS energy loss (and Bhabha cross section for Tcut < |
---|
| 9 | Tmax, with correction or without it, it does not play any substantial role) may be |
---|
| 10 | used, as it was earlier. But it takes place only for rather low muon energies. |
---|
| 11 | 4) Tmax > Tbound, with three possibilities for Tcut: |
---|
| 12 | 5) Tcut < Tbound: restricted BBS energy loss (< Tcut), numerical calculation of the total |
---|
| 13 | cross section with accurate formula and sampling with accurate formula are needed. |
---|
| 14 | 6) Tbound < Tcut < Tmax: for energy loss it is necessary to take usual restricted BBS |
---|
| 15 | (< Tbound) plus twice restricted numerically integrated energy loss for the interval |
---|
| 16 | (Tbound,Tcut), total cross section and sampling being similar to preceding point. |
---|
| 17 | 7) Tcut > Tmax: restricted BBS (< Tbound) plus twice restricted numerical (Tbound, |
---|
| 18 | Tmax); discrete interactions are not simulated. |
