General Comments:

34P identified and produced in bombardment of chlorine with fast neutrons (1946Bl01, also Zunti and Bleuler, Helv. Phys. Acta 18, 263 (1945)); measured half-life. In a paper by J.M. Cork and W. Middleton, Phys. Rev. 58, 474 (1940), a 12.7-s activity was found and ascribed to a phosphorus isotope of mass greater than 31.

34P is of some relevance in connection with approach to the so called ’island of inversion’

Measurement of strong absorption radius: 1999Ai02: Si(34P,X) reaction at 38-80 MeV/nucleon, NSCL facility. The 34P beam was obtained from fragmentation of 55Mn beam with 9Be target at 50-90 MeV/nucleon, NSCL facility.

Q-value: Note: Current evaluation has used the following Q record

Q-value: S(2n)=16386.5 8, S(2p)=28065 86 (2011AuZZ)

Q-value: Values in 2003Au03: Q(β-)=5374 5, S(n)=6251 5, S(p)=11354 17, Q(α)=-11110 15, S(2n)=16395 5, S(2p)=28070 90

Q-value: Mass excess=-24548.71 keV 81 (2009Kw02) is considered in 2011AuZZ evaluation
