Abstract

The influence of hyperfine deorientation in recoil-distance Doppler shift measurements was studied for high spin states in

{}^{38}{Ar}

,

{}^{40}K

,

{}^{41}K

, and

{}^{41}{Ca}

having lifetimes in the range between 30 ps and 10 ns. At a recoil velocity of

\frac{v}{c} = 0.02

, deorientation in vacuo was found to be negligible for lifetimes up to several ns.
