首次测量了短寿命β发射体~（13）O和~（23）Mg注入Pt的自旋弛豫时间T_1，T_1（~（13）O）= 2.90 ± 0.65Ks，T_1（~（23）Mg）= 1665 ±140 Ks。在300 K下测量了Pt中13 O的奈特位移，为beK（13 O）= +（4.23 ±0.14）× 10 - 3。在13 O的情况下，骑士位移是异常大，弛豫时间是异常快的Pt与其他间隙杂质相比。一个KKR能带结构计算再现目前的大奈特位移相当不错。
The spin relaxation timeT1for short-lived beta emitters13O and23Mg implanted in Pt have been measured for the first time;T1T13O) = 2.90 ±0.65 Ks andT1T(23Mg) = 1665 ±140 Ks. The Knight shift for13O in Pt was measured at 300 K to beK(13O) = +(4.23 ±0.14) × 10−3. In the case of13O, the Knight shift is unusually large and the relaxation time is unusually fast compared with other interstitial impurities in Pt. A KKR band-structure calculation reproduces the present large Knight shift fairly well.
