A theoretical expression is derived for the difference {Delta}E{sub L}(1s{sub 1/2})-8{Delta}E{sub L}(2s{sub 1/2}) in Lamb shifts for the hydrogen atom. The obtained value of the difference is found to be equal to {minus}187.236(11) MHz. The leading logarithmic corrections to the lifetime of the 2p{sub 1/2} level are calculated, and the new value of the lifetime is found to be equal to 1.596 1887(15)X10{sup {minus}9}s. The existing experimental data on the ratio of the width of this level to the Lamb splitting and the radiative corrections obtained in the investigation are used to obtain new values of the Lamb shift: E(2s{sub 1/2})-E{sub 2p}{sub 1/2}=1057.8576(21) MHz, {Delta}E{sub L}(2s{sub 1/2})=1045.0213(26) MHz, and {Delta}E{sub L}(1s{sub 1/2})=8172.934(24)MHz. 24 refs.
