Recently Reynolds, Hayden and Hardy analyzed atomic deuterium lifetimes in a cell with walls covered by a saturated [sup 4]He film. They were able to determine the deuterium chemical potential in [sup 4]He and also discussed the possibility of estimating its effective mass. These measurements inspired the authors attempt to understand the properties of hydrogen isotope impurities in liquid [sup 4]He using the extended Jastrow-Feenberg theory based on the correlated wave function. Here the results for hydrogen isotope chemical potentials in the bulk [sup 4]He as a function of density are presented. The accuracy of the method is tested by calculating the chemical potential of the [sup 3]He impurity. Good agreement is found with existing measurements. The effective masses of the hydrogen impurities are also calculated. For deuterium the authors predict a value m[sub eff] = 4 m[sub D].
