Nuclear data sheets for A = 45

Abstract

Level schemes, spin and parity assignments, and decay properties are presented for all nuclei with mass number A = 45. Experimental data and adopted values are given along with conclusions as to the best spin and parity assignments. The presentation of the nuclear properties is given in the light of the data and current theoretical ideas. Inconsistencies in the data are discussed wherever they are noted by the compiler.

While a few levels in each of the A = 45 nuclei appear to be well represented as ‘shell model’ states, it is clear that there are many more low-lying states than have been accounted for by model calculations.

Few data exist as regards high-spin states (J > 7/2) expected in this region. No gamma-decay data have been reported for ⁴⁵K levels. The fine structure of isobaric analog levels in ⁴⁵Ti has not been examined.

All the tabulated C²S and C²S' direct-reaction strengths are derived from distorted-wave Born approximation reaction theory. The reader is referred to the individual papers for details of the calculations.

The adopted level and decay properties are based on data received before March 1970.
