GAMMA RADIATION EFFECTS ON ISOPRENOIDS. III. 2-METHYLBUTENE-2 AND 2-METHYLBUTANE

Hydrogen and methane radiation yields (molecules per 100 e.v. absorbed) were determined for 2methylbutene-2 and 2-methylbutane. G(H2) and G(CH4) are 1.15 and 0.20 respectively for 2methylbutene-2, and 4.60 and 0.57 respectively for 2-methylbutane. The hydrogen and methane yields are linear with dose...

Description
Summary:Hydrogen and methane radiation yields (molecules per 100 e.v. absorbed) were determined for 2methylbutene-2 and 2-methylbutane. G(H2) and G(CH4) are 1.15 and 0.20 respectively for 2methylbutene-2, and 4.60 and 0.57 respectively for 2-methylbutane. The hydrogen and methane yields are linear with dose at low conversions. The value of G(H2) for 2-methylbutene-2 fits a relationship, which defines G(H2) for rubber-type isoprenoids (such as 2,6-dimethyloctadiene-2,6, squalene, and rubber) in terms of the number of their isoprenoid units, so that G(H2) = 0.48 (1 plus 1.4/I) where I is the number of isoprenoid units.
