Nuclear Data Sheets for A = 44
The experimental data are evaluated for known nuclides of mass number A=44 (Si,P,S,Cl,Ar,K,Ca,Sc,Ti,V, Cr,Mn). Detailed evaluated level properties and related information are presented, including adopted values of level and {gamma}-ray energies, decay data (energies, intensities and placement of radiations), and other spectroscopic data. This work supersedes earlier full evaluations of A=44 published by 1999Ca45 and 1990En08 (also 1998En04 update). No excited states are known in {sup 44}Si, {sup 44}P, {sup 44}Cr, {sup 44}Mn. Only one excited state is known in 44V and its Isobaric Analog State (IAS) has been observed but with the level energy not known. Information for {sup 44}S, {sup 44}Cl and {sup 44}Ar is limited and their radioactive decay schemes seem incomplete in view of large Q values and known excitations much below than allowed by Q values. The {sup 44}Ca, {sup 44}Sc and {sup 44}Ti nuclides remain as the most extensively studied from many different reactions and decays.
