The time differential perturbed angular correlation technique was used to measure the hyperfine magnetic field acting on 41 K nuclei recoil implanted in nickel by the 41 K(p, p′) 41 K reaction. From the modulation of the time spectrum of the gamma transition from the 7/2 − statc at 1293 kcV, H (K Ni) = (− 19.9 ± 1.2) kG is found. From the unperturbed p 2 − 1293 keV gamma ray angular correlation, studied with a silver backing for the 41 KBr target, values A 2 = 0.246 ± 0.064 and A 4 = −0.042 ± 0.103 of the angular correlation coefficients were obtained. The amplitude of modulation of the time spectrum amounts to about 60% of that derived from the unperturbed angular correlation coefficients.
