IR absorption spectra of excess electrons, selflocalized in bubbles in solid hcp4He and bcc3He, are measured. The pressure dependence of the 1s−1p transition energyE1s1pcan be fitted by the values, calculated using spherical rectangular well model and taking surface tension to be pressure independent. The bubble radius obtained varies smoothly from 10.7 Å at 45 atm to 9.4 Å at 100 atm, no dependence on crystalline structure as well as on isotope composition has been observed. The 1s−1p linewidth is 5–6 times smaller thanE1s1p.The absorption cross section is estimated to be 12 Å2.
