Dissociative recombination of HeH+ isotopes with an ultra-cold electron beam from a superconducting electron cooler in a storage ring

We found mistakes in our theoretical calculations in figure 2, page L300. The correct figure appears below. In addition, discussions based on the incorrect calculations should be removed. That is, in page L302, the statement from the latter clause in the 8th line ` ... , although there remains ... ' to the end of the paragraph ` ... dissociative state density.' should be deleted. Figure 2. Comparison of the relative experimental DR rate coefficients (dots) of helium-hydride isotope ions with the corresponding theoretical calculations (absolute values). The experimental rates are arbitrarily scaled in magnitude to facilitate a comparison with theory. The error bars indicate statisical errors.
