Abstract

We have directly observed a time-dependent recoilless fraction. This effect is seen using delayed-coincidence Mössbauer spectroscopy. The time-dependent recoilless fraction is observed at the ${Fe}^{3 +}$ site and not at the ${Fe}^{2 +}$ site in a CoS $O_{4}$ ·7 $H_{2}$ O source. The relaxation time of the recoilless fraction is estimated to be between 10 and 100 nsec. Delayed-coincidence Mössbauer spectroscopy measurements on sources of Co ${Cl}_{2}$ ·6 $H_{2}$ O and Co ${(N H_{4})}_{2}$ ${(S O_{4})}_{2}$ ·6 $H_{2}$ O did not show such an effect.
