Question

The stability of 3, CI with respect to alpha, beta-plus and beta-minus decay is to be determined. The following atomic masses are known: 15 He: 4.002603 u 32P:31.973907 u 36 S:35.967081 u 1%CI: 35.968307 u 38 Ar:35.967546 u 16 18 Is the Cl nucleus subject to beta-plus decay only, beta-minus decay only, beta-minus or beta- plus, alpha-decay only, or none of these? Explain why. Show your work for full credit.

Answer 1

& decay 32 a 15P + He 2 Now the energy Yobtenu do not & value = (31.973907 + 4.002603 35.96 8307) x 931.5 mer - 923.86 Meu 36 reaction me As a value is negetive this not happen sponteniousty stable with respect to alpha decay Hence ß decay 36 & Artß 17 35.968307 & value = 967546 +5.5810- X 931.5 new As 2-12 431 mer & value is negetive it is stable with respect to 8 decay 36 a ßt dcay +ßt ovalne = (5.9 is.getofl +5x10 - 35.967546) X 93115 - 1.142 Mer. As a value is negetive it is state with respect to ßt decay.
