    "abstract": "We have developed a theoretical method for interpretation of photoionization\nexperiments with the H_3 molecule. In the present study we give a detailed\ndescription of the method, which combines multichannel quantum defect theory,\nthe adiabatic hyperspherical approach, and the techniques of outgoing Siegert\npseudostates. The present method accounts for vibrational and rotation\nexcitations of the molecule, deals with all symmetry restrictions imposed by\nthe geometry of the molecule, including vibrational, rotational, electronic and\nnuclear spin symmetries. The method was recently applied to treat dissociative\nrecombination of the H_3^+ ion. Since H_3^+ dissociative recombination has been\na controversial problem, the present study also allows us to test the method on\nthe process of photoionization, which is understood better than dissociative\nrecombination. Good agreement with two photoionization experiments is obtained.",
