Weak and strong decay rates and the associated emitted powers are calculated using a semiclassical approach. Our results are discussed with respect to distinct ones in the literature, which consider the decay of accelerated protons in electromagnetic fields. A number of consistency checks are presented along the paper.11engArtigo10.1103/PhysRevD.74.045032WOS:000240239500117Acesso abertoWOS000240239500117.pdf
