The potential energy curve of helium dimer is found to become attractive when the laser intensity is sufficiently high, and the previous prediction [T. Yasuike and K. Someda, J. Phys. B 37, 3149 (2004)] based on the Kramers-Henneberger high-frequency approximation is confirmed. Under appropriate laser conditions, the lifetime is found to be sufficiently long to discretize vibrational states, owing to the nonperturbative stabilization effect in photoionization.}, title = {Lifetime of metastable helium molecule in intense laser fields}, volume = {78}, year = {2008} }
