Electric-field-induced helium-helium resonances
Copyright policy )Electric-field-induced helium-helium resonances
The tunability of the helium-helium interaction through an external electric field is investigated. For a static external field, electric-field induced resonances and associated electric-field induced bound states are calculated for the $^4$He-$^4$He, $^3$He-$^4$He, and $^3$He-$^3$He systems. Qualitative agreement is found with the literature for the $^3$He-$^4$He and $^3$He-$^3$He systems [E. Nielsen, D. V. Fedorov, and A. S. Jensen, Phys. Rev. Lett. {\bf{82}}, 2844 (1999)]. The implications of the predicted electric-field induced resonances for $^4$He-$^4$He on the wave packet dynamics, initiated by intense laser pulses, are investigated. Our results are expected to guide next generation experiments.
