- 中文摘要: 在 =35 MeV 時 Mg(p,n)A反應中,我們觀測到三個, T=0 → , T=1 Gamow-Teller躍遷。這三個 , T=1在A核中的受激態分別處於 = 0.44, 1.12及3.06 MeV,我們用Brown及Wildenthal的波函數,M3YE+TN(odd)有效核成子一核成子交互作用作DWBA分析,其結果十分良好。由低能量(p, n)反應的反應截面得出GT躍遷到態的β衰變率。
- 英文摘要: Three , T=0→, T=1 Gamow-Teller transitions are observed in the Mg(p,n)A reaction at= 35 MeV. The three , T=1 states are 0.44, 1.12 and 3.06 MeV in A. DWBA analyses with Brownand Wildenthal wave function and M3YE+TN (odd) effective nucleon-nucleon interaction give satisfactoryresults. Resonable comparison between the low-energy (p, n) cross-section and the β-decay rates has beenobtained for the GT transitions leading to the states.
