The effects of various additives, SF<SUB>6</SUB>, NH<SUB>3</SUB>, C<SUB>2</SUB>H<SUB>5</SUB>OH, N<SUB>2</SUB>O, NO, SO<SUB>2</SUB>, and C<SUB>2</SUB>H<SUB>4</SUB>, on the product yields in the γ-radiolysis of liquid <I>n</I>-hexane at room temperature have been investigated. The following conclusions have been drawn: (i) The added SO<SUB>2</SUB> acts mainly as a radical scavenger. (ii) The added NO shows not only the effect of radical scavenging, but also other effects. Therefore, it is inadequate to use NO as a simple radical scavenger, (iii) The C<SUB>7</SUB>-C<SUB>12</SUB> products are formed from a combination reaction of alkyl radicals, but not from an ion-molecule reaction, (iv) The formation of C<SUB>6</SUB>H<SUB>13</SUB><SUP>+</SUP> ions by the direct action of radiation is suggested, (v) The <I>G</I>-value of ionization is evaluated to be 4.0. A brief discussion concerning the formation of N<SUB>2</SUB> in the presence of N<SUB>2</SUB>O is also given.
