Abstract

The pulse-height distributions for131mXe in PPO solutions of aliphatic hydrocarbons such as n-pentane, n-hexane, n-heptane, 2,4-dimethylpentane, 2,3,4-trimethylpentane, 1-pentene, 1-hexene and 1-heptene are investigated as a function of temperature. The pulse-height distributions are found to be shifted toward higher pulse-heights with decreasing temperature. The count rates of131mXe remain unchanged with decreasing temperature. The mechanism of the effect is also discussed.
