Abstract
The Knight shifts K for short-lived β emitters 12N and 27Si implanted in Pt have been measured by means of β-NMR technique. The results were K(12N in Pt) = +(5.8 ± 2.1) × 10-4 and K(27Si in Pt) = +(1.4 ± 0.8) × 10-3. The spin-lattice relaxation time T1 was measured for 12N in Pt. The result was T1(12N in Pt, T = 300 K) = 66 ± 8 ms, thus, T1T = 20 ± 2 Ks. The present Knight shifts are in good agreement with the KKR band structure calculation with local lattice relaxation determined theoretically.
