  ABSTRACT: We studied the excitation spectra in the case of Xe@(p-H2)n embedded in a solid-state parahydrogen, making use of the ab initio molecular orbital method (QMO), in order to seek the possibility of the radiative emission of the neutrino pair (RENP) process that may be associated with the E1 × M1 transition processes. By means of a QMO calculation, the remarkable matrix effect was found in the structure of the electronic states. Three E1-type excitation bands (ε1, ε2, ε3, in the order of increasing energy) in the UV absorption were found. In the present preliminary calculation, the second was too close to be clearly/well distinguished as an independent peak observed in the last experiment. Nevertheless, across the second (ε2) band, two associated bands that may link to the M1-type transition were found. Therefore, the M1-type de-excitation process may be probable with the help of intensity borrowing from the ε2 band, which may support the probability of the RENP process.
