Study of the Effect of Newly Calculated Phase Space Factor on β-Decay Half-Lives

Table 6

State-by-state comparison of calculated PSF (for /EC-decay) using recipe of [17] and current prescription (TW). Shown also are the daughter energy levels, nuclear matrix elements NME, values, partial half-lives (PHL) for /EC-decay, and branching ratio of the selected nuclei.
