Parity nonconservation in the γ decay of polarized17/2−isomers inTc93

subject

description

The determination of the ${0}^{\ifmmode^\circ\else\textdegree\fi{}}\ensuremath{-}{180}^{\ifmmode^\circ\else\textdegree\fi{}}$ asymmetry (${A}_{\ensuremath{\gamma}}$), which arises because of the parity nonconserving matrix element, in the 751-keV \ensuremath{\gamma} decay of polarized $17/{2}^{\ensuremath{-}}$ isomers in $^{93}\mathrm{Tc}$ with respect to the direction of polarization is reported. A combined analysis of the present results together with those from our earlier work yields an effect of two standard deviations.
