| 英文摘要 | \the changes of decay rates of radionuclide (111)in (electron capture) and (32)p (beta decay) induced by external mechanic motion are studied. the results indicate that, in the external circular rotation in clockwise and anticlockwise centrifuge on northern hemisphere (radius 8 cm, 2000 r/min), the half life of (111)in compared with the referred (2.83 d) is decreased at 2.83% and increased at 1.77%, respectively; the half life of (32)p compared with the referred (14.29 d) is decreased at 3.78% and increased at 1.75%, respectively. when the clockwise and anticlockwise rotations increase to 4000 r/min, the half life of (111)in is decreased at 11.31% and increased at 6.36%, respectively; the half life of (32)p is decreased at 10.08% and increased at 4.34%, respectively. when the circular rotation is removed, the decay rates of (111)in and (32)p return back to the referred, respectively. it is found that the external circular rotations in clockwise and anticlockwise centrifuge selectively increased and decreased the decay rates of (111)in and p-32, respectively, and the effects are strongly dependent on the strength of circular rotation. it is suggested that these effects may be caused by the chiral interaction. |
