Description
Recently, two experiments in Hall C at Jefferson Lab finished data taking. One experiment focused on a precision measurement of the virtual photon asymmetry A$_1^n$ at large values of Bjorken-x (0.61 < x < 0.77) at various values of Q$^2$, and the other experiment measured the spin structure function g$_2^n$ over a large range of Bjorken-x (0.20 < x < 0.95) to extract the Q$^2$ evolutions of the twist-3 matrix element, d$_2^n$(Q$^2$), at three different values of Q$^2$ (3.0 GeV$^2$ < Q$^2$ < 5.60 GeV$^2$). Details of the experiments and an update of the data analyses will be presented.
