We have measured the probabilities of delayed fission in electron capture for the nuclei /sup 240,242/Bk, /sup 244,246,248/Es, and /sup 248,250/Md. The data are analyzed by means of analytical expressions obtained in the work which explicitly relate the probability of delayed fission (in electron capture or ..beta../sup -/ decay) to the parameters of a two-humped fission barrier. As a result of the analysis the fission barriers are evaluated for the corresponding daughter nuclei: the isotopes of Cm, Cf, and Fm. According to the estimates the height of the fission barrier for the group of nuclei investigated is close to the value 6 MeV and does not decrease appreciably with increase of the Z of the nucleus or with removal from the ..beta..-stability band.
