Charged particleQvalues for reactions on C, Cr, Fe, Co, and Ni

$Q$ values were measured for 27 reactions on targets of ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{54}{}_{}{}^{}\mathrm{Cr}$, ${}_{}{}^{54,56}{}_{}{}^{}\mathrm{Fe}$, ${}_{}{}^{59}{}_{}{}^{}\mathrm{Co}$, and ${}_{}{}^{58,60,62,64}{}_{}{}^{}\mathrm{Ni}$ with resulting uncertainties of 0.7 to 3.2 keV. Care was taken to define sources of error. A ${\chi }^2$ test on an interconnected set of 19 measurements indicates internal consistency and a comparison of eight ($d,p$) $Q$ values with ($n,\gamma$) numbers shows excellent agreement. A mass evaluation was performed on a truncated region centered on Co. The results indicate that the 1971 values for the masses of ${}_{}{}^{55}{}_{}{}^{}\mathrm{Cr}$ and ${}_{}{}^{55}{}_{}{}^{}\mathrm{Co}$ are in error. The uncertainties of the masses of ${}_{}{}^{53}{}_{}{}^{}\mathrm{Fe}$ and ${}_{}{}^{61}{}_{}{}^{}\mathrm{Co}$ are greatly reduced. The question of the ${}_{}{}^{57}{}_{}{}^{}\mathrm{Fe}$ mass raised in The 1971 Atomic Mass Evaluation is not entirely resolved and consequently the absolute values of some masses in this region are still uncertain to about 5 keV although the $Q$ values are improved.
