Effects of variation of the fine structure constant α and quark mass m_q in Mossbauer nuclear transitions

NUCLEAR STRUCTURE ⁵⁷Fe, ⁶⁷Zn, ⁸³Kr, ⁹⁹Ru, ¹¹⁹Sn, ¹²¹Sb, ¹²⁵Te, ^127,129I, ¹⁴⁹Sm, ^151,153Eu, ^155,157Gd, ¹⁶¹Dy, ¹⁸¹Ta, ¹⁹⁷Au, ²²⁹Th, ²³⁵U, ²⁴³Am; analyzed nuclear structure data, information on change of rms charge radius and intrinsic quadrupole moment between ground and excited states; deduced sensitivity of nuclear (Mossbauer) transitions to variation of fine structure constant and quark mass. Discussed the possibility of studies 8-eV in ²²⁹Th and 76-eV in ²³⁵U transition by means of laser spectroscopy.
