Spectroscopic Amplitudes at the Vertices of the ^28𝐒𝐢→ p+^27 Al and ^30𝐒𝐢→ t+^27 Al Virtual Decays

The spectroscopic amplitudes of the virtual decays of silicon isotopes ^28(30)Si(J_B)→ p(t)+^27Al(J_A) have been obtained using the wave functions of the 1d-2s -shell nuclei in the Nilsson model. It has been shown that correct spectroscopy of the 1d-2s -shell nuclei and consideration of their deformation has a significant effect on the values and signs of the spectroscopic amplitudes of both protons and tritons.
