Precision measurement of the last bound states in H $_{2}$ and determination of the H + H scattering length

K. -F. Lai, W. Ubachs, M. Beyer

The binding energies of the five bound rotational levels $J = 0 - 4$ in the highest vibrational level $v = 14$ in the X $^{1} I^£_{g}^{+}$ ground electronic state of H $_{2}$ were measured in a thre…
