A Monte-Carlo method is used to model track formation during slowing d
own of an electron with an initial energy of 1 MeV in pure liquid wate
r, the dynamics of the spatial distribution of the primary radiolysis
products, and the inhomogeneous kinetics of chemical reactions within
a track. Five degrees of ionization and the production of five singlet
excited states of water, as well as collective excitations of a plasm
on type, are taken into account. The calculated yields of ion and radi
cal pairs before the onset of chemical reactions were 5.24 pairs/100 e
V of e-.. H2O+, 1.98 of OH .. H, and 0.77 of H-2 .. O, while the yield
s of the radiolysis products from water after completion of the reacti
ons in the centers were 2.92 of e(ag) per 100 eV, 3.5 of H3O+, 3.02 of
OH, 0.64 of H, 0.73 of H2O2, 0.46 of H-2, and 0.58 of OH-.
