Probability of favorable alignment for anomalous positron-electron pair emission through vacuum decay is calculated. The calculated small favorable alignment probability value of 0.116 is found to be enhanced by about 16% in comparison with the results of a similar study using a fixed moment of inertia as well as the results from a semiquantal calculation reported earlier.1347-1350engArtigo10.1103/PhysRevC.45.1347WOS:A1992HJ69200046Acesso restritoWOSA1992HJ69200046.pdf
