Probing for high momentum protons in $^{\mathrm{4}}$\textit{He} via the $^{\mathrm{4}}$\textit{He(e,e'p)}$^{\mathrm{3}}H$ reaction.

The structure and dynamics of $^{\mathrm{4}}$\textit{He} can be studied through $^{4}$\textit{He(e,e'p)} coincidence measurements at high momentum transfers. Using the Hall A high resolution spectrometers and a cryogenic $^{4}$\textit{He} target, the short range correlation E07-006 and E08-009 experiments held in Hall A of Jefferson Lab measured the entire range of missing momentum from 0.0 GeV/$c$ to 0.9 GeV/$c$. Experimental cross sections for the 3-body breakup $^{4}$\textit{He(e,e'p)}$^{3}H$ up to $P_{miss} \quad =$ 0.632GeV/$c$ at $x_{B} \quad =$ 1.24 and $Q^{\mathrm{2}} \quad =$ 2(GeV/$c)^{\mathrm{2}}$ are reported. The data are compared to Relativistic Distorted Wave Impulse Approximation (RDWIA) calculations.
