英文摘要If is there enhanced sensitivity to variations of fine structure constant, nucleon mass and meson masses in the transition between the low energy and long-lived nuclear isomer and ground states? To answer this open problem, we investigate the transition between the long-lived 7.6 +/- 0.5 eV isomer and ground states in Th-229 based on the formulae derived from both the Nilsson model and Feynman-Hellmann theorem. Consistent conclusions are drawn by these two method. The sensitivity to relative variation of fine structure constant could be enhanced by 3-4 orders of magnitude, and to variations of nucleon mass and meson masses axe enhanced by about 5-6 orders of magnitude in the Th-229 transition.
