Identification: on-line ms of cerium(p,spallation) 1969Ha03, 1971Ho07, 1972Ho18

Q(¹¹⁵Xe)-S(p)(¹¹⁵I)=6200 130 from β⁺/p (1972Ho18) (β⁺)(p) coin

(p)(γ) coin: Iγ(γ^|+)=28 4, Iγ(709γ,¹¹⁴Te)=58 7 (1972Ho18)

Measured (p)(709γ,¹¹⁴Te) coin indicates 58% 7 proton branching to first excited (2⁺) state in ¹¹⁴Te, 42% decay to (0⁺) g.s.

β^- strength function (1975Ho03) theory: (1985Ar18,1984Al19)

Q-value: Note: Current evaluation has used the following Q record -9.0×10³ SY9642 16 3.1×10³ syst 2506 14 2011AuZZ

Q-value: ΔQ(β^-)=300 2011AuZZ
