摘要：

The hydrogen loss behavior in polymers under heavy ion irradiation is investigated for different electronic excitation energies. It is found that hydrogen loss under ion irradiation depends on the electronic energy deposition, and the type of bonds present in it. It is noticed that the hydrogen loss curve can be fitted with an equation containing two exponential terms. The diminishing of hydrogen loss at higher fluences is discussed on the basis of overlapping of ion tracks.
